I also had (ahem) "access" to 6 of the full-length Kaplan test questions but couldn't take them under simulated conditions. I only did the science sections and probably scored 23-25 Total Science on all of them. More on Kaplan below.

Destroyer Bio: Not bad I guess, but if you're memorizing all 500-some problems and banking on that to do well in this section, you're going to be sorely disappointed. Nothing replaces doing well in bio courses (especially upper-div ones) for this section.

Destroyer GC & Orgo (2 runs): Terrific.

Destroyer GC: 85-90% 1st run, almost 100% 2nd run
Destroyer Orgo: 80-85% 1st run, probably like 95% 2nd run

Math Destroyer: Terrific. The actual test is easier than Math Destroyer.

3 runs, last run's average = 24.

DATQVault:

Quite good, I liked the layout, I liked the questions. I paid for a $20 sub.

Crack DAT Reading:

Did 9/10 tests, averaged 22 & scored 22 on the real thing. I've bashed CDR before because when I compared it to ADA 2009 RC, it was nothing like it; but actually, it's quite representative of the real thing. ADA 2009 RC is much, much more difficult.

Crack DAT PAT:

Did 10/10 tests, averaged 25 & scored 25 on the real thing. I think it's okay but a little over-rated. More on that below.


The actual test:

Bio: I was actually pretty impressed with some of the questions they had on here. There was one in particular that was very tricky. More than a couple required upper-div bio knowledge imo, but most were very straight-forward. I took 30 minutes on this section, which caused me a lot of panic heading into GC (slowest section).

GC: Disappointed in this section. GC is my best subject and I had very little problems with Destroyer. A large majority of the questions I missed in my practice tests were due to careless mistakes rather than lack of knowledge. I'm guessing careless mistakes factored into my score as well. To be honest, I expected a 30 in this section because I didn't miss any in the 2009 ADA, but questions on my test were so much tougher than the ADA 2009 GC section and I'm sure I made bone-headed mistakes. However, GC on the real test is tough. YOU NEED TO BE PREPARED TO DO MANY INTRICATE CALCULATIONS. DO DESTROYER GC WITHOUT A CALCULATOR. The math in this section was tougher than QR (100% serious). I had read many breakdowns in the past stating that equations are set up for you, and while that is true for some problems, I had 2 problems where we had to do a lot of complex long division to achieve the correct answer. Destroyer GC is very representative of this section.

Orgo: Very simple and straightforward, Destroyer is very good for this section as well, but problems were much easier. There was maybe 1 tricky question I think. Chad's + Destroyer = good combo. ADA 2009 is more difficult.

PAT: Apparently, ADA fixed the crappy PAT images that people complained about in the past. It looks just like CDP now (computer-generated lines instead of scanned and uploaded), so don't worry about getting fuzzy images or anything. CDP's keyholes + pattern folding are just not that great imo. All other sections are representative (except you can't count lines as much as you can on TFE during the real test). For keyholes, the best sources are: Kaplan online tests, ADA 2007, ADA 2009, & Top Score. I feel those were the most representative. Ditto for pattern folding (same 4 sources). CDP's pattern folding emphasizes knowing how to place lines and dots (like those dice questions). In reality, there are many more q's where you need to fold patterns that don't have markings on them.

RC: CDR = awesome. I got the "dreaded" ethic passage, but I thought that one was incredibly easy. S&D is the best method for this section. Here's something funny: in practicing with CDR, I had always read the passage first (rather slowly, trying to understand everything) before answering questions. On the actual test, I very quickly realized that after the first passage, S&D is the best method. I probably missed the most questions on the first passage where I didn't S&D. It's pretty ridiculous because if the passages were on the level of ADA 2009 (which I took to be most representative of the real thing), I'm pretty sure reading first would have been a better method (hence, that's how I practiced). So for those of you reading this, I took a bullet for you guys. Do S&D.

QR: Math Destroyer is so, so, so incredibly good for this section. If you master Math Destroyer, you'll be fine. Actual test = easier as well. I had 2 problems where the concepts didn't show up anywhere in Math Destroyer though, but they weren't too tough. It is very easy to be careless in this section, so if you're good at math, go thru this section slowly and carefully. I know for some of you it's tough to even finish on time, so you have to practice and practice.

Reviews of other material:

Chad's: Great. Won't say more because everyone knows this already.

Top Score: Tougher than the actual DAT I think, it tests on some pretty obscure stuff in GC & OC. But I liked it very much. Top Score RC is a bit too easy. I got a 29 on the first RC test and would have gotten higher on the 2nd and 3rd ones if I hadn't pooped out. Good practice for S&D though I guess.

Cliffs: Good for general review I suppose, but insufficient if you want a higher score.

KBB: Terrible, stay away.

Schaums: Great, very comprehensive, get this.

Campbells: The ultimate source, get this.

Kaplan Online Tests: GC & Orgo were pretty good, but Bio was actually terrible. They just recycled the same concepts over and over in all 6 of their tests, so the scope is very limited. I loved its TFE, Keyholes, and Pattern folding though, better than CDP in those 3 sections.

Final thoughts:

I know some of you are going to take this the wrong way, but hey, I posted this long and helpful breakdown so I'm going to say it anyways. I'm a little disappointed in my score. I aimed for a 25, and on a better day I think I would have gotten it. Especially annoyed at GC because I think I understand almost all of its concepts very well, but I suppose it's my own fault. Too many careless mistakes that I always made even during practice tests, should have cleaned up in that area before the real thing. What are you gonna do? 🙄

I'm applying to 13 schools. I have a 3.95 BCP GPA and a 3.93 Cumulative GPA, so the academic part of my application is set. My EC's are probably pretty weak though in comparison. My dream school = UCLA, so fingers crossed for that.


Anyways, if you have questions, ask away.

Edit:

Wanted to add some more stuff about PAT.

Keyholes: I was wondering about this until yesterday even, but now that I've taken the test, I know the answer. Absolute size does not matter, only proportions do.

TFE: Line-counting will only get you so far. They are correct when they say "Visualize!"

Angles: It's not as hit-and-miss as people say. You can do well on this if you practice. I used a lot of methods for this section. For smaller, acute angles, I like corndog's method of looking close to the vertex and moving your eyes back and forth to get a sense of the width at the tip. For larger acute angles, I used the hill method sometimes as well as corndog's method. For obtuse angles, I like drawing an imaginary line and looking at the supplementary angle to compare. Angles are key to a high PAT score. It may seem impossible the first go, but if you keep practicing, you'll get there. Real DAT = a little easier than CDP. I probably practiced the most for this section.

Hole Punch: Don't use the grid method. It's a complete waste of time imo, even if you've drawn them out before you begin. I always used my fingers on the table to represent the dots, lol. If you do this, it probably will shave your time drastically. I used the grid method initially and it just took me forever (maybe I just suck at drawing dots, lol). With my fingers method, I blew thru these sections in about 3 mins each time. Took longer on the real DAT though because I checked it after every time. Real DAT = a little easier than CDP for this section.

Pattern Folding: This & Hole punch are probably my best sections. I think I've missed 1 pattern folding question in the last like 200 I've done, lol. 😛 My advice: DO NOT fold it. It's so much easier working in 2D than 3D. Move pieces around in your head in 2D rather than folding it in 3D. That's some GREAT advice right there for this section.

You think Campbells will be sufficient for Bio?
I've had bio out of order so I'm pretty much missing Ecology and Evolution section. You think campbell will cover it enough?

Everything that could possibly be on the DAT will be in Campbell's, I've heard they get their questions out of the book.
 
All I know is that you seem to have a deep depth of bio knowledge. Perhaps too deep for the DAT, but I have high expectations of you

Honestly that's mainly because of the masters program I went through. And now I really believe it's the graduate level related questions that make bio look really hard. Normally it's the stuff that are not covered in undergrad bio classes. I took the DAT once before my graduate program and all the WTF questions on my DAT were all covered in my masters.
 
Everything that could possibly be on the DAT will be in Campbell's, I've heard they get their questions out of the book.

I also heard the exact same thing. However, how did you go about studying the Campbells book? Ironically, my brother had the second (yes, 6 editions ago) for his summer program that he did at Northwestern 7 years ago... and it was way in the back of my dusty old bookshelf at home (IT'S A SIGN!!!!! jk). But anyways, I think the book is too huge and vast in information to review from, no? I heard it was best to just review chapters 19-21.. from several other people. How did you utilize Campbell's? Did you take notes from every chapter (dang), write down the summaries after every chapter, or just read through each chapter thoroughly. I have Schaum's, Cliffs, and Campbell's for review materials (I'll get destroyer and qvault later on).... but I'm trying to figure out the best method to go about using all those materials effectively when I start studying soon. I'm also a biology major at umich, so naturally, it should come a bit easier to me.

Also, you preferred Schaums Outline of Biology over Cliff's AP biology? I heard from a lot of people that Cliff's AP Biology is the way to go. I haven't looked at either yet (however, get this... i also found a dusty OLD Cliff's AP biology 2nd edition that my brother used just for his highschool ap biology class 7 years ago... ANOTHER SIGN 😀 ). Can you elaborate why Schaum's was better than Cliffs?

And lastly, I've done a about 40-50 PAT problems already (just to see what they are like) and I am doing well on them. They're actually really easy for me. I feel like I'm just "gifted" at visualizing all the angles, hole-punching, etc. Is that the right way to go about it on the exam? I heard there were a lot of methods and whatnot... yet I just literally visualize the pictures and they seems pretty easy......... it's actually fun.....

Lastly, great job on your scores. Also 3.9 BCP from YOUR school is off the walls-ridiculous, my goodness.

I'm going to assume you did well in your undergrad courses and remember the main points of the important topics in bio. I think for people like that, the best way to study for bio ISN'T to go thru a book sequentially and take notes on things. I did this for a while when I started studying from Cliffs and just felt it was a waste of time because I knew the basic stuff (i.e. cellular bio) already.

The best way is to go identify topics you don't know much about and read up on that in either Schaum's or Campbell's. Campbell's is really great for illustrations and diagrams, but if I didn't feel like dealing with figures and just wanted a basic run-down I used Schaum's. Then, I used Anki (flashcard program) and made flashcards for all the facts I didn't know as I went thru the chapter.

DATQVault is probably really useful for identifying topics that you need to work on btw.

Schaum's > Cliffs because Schaum's is more comprehensive. Cliffs is good for getting the main points of things, so for Plants and Bio diversity (topics which I was fairly certain the DAT wouldn't test too deeply into) that's all I used. For physiology, Schaum's is really good because it has a lot of detail but also is to the point. I guess Schaum's is the intermediate between Campbell's and Cliffs.

For PAT, yes, visualization is everything. There are strategies like line-counting for the TFE section, but that will maybe work for a couple of problems on the real DAT and won't get you far. Which source are you using btw for PAT? I will be seriously impressed if you're using CDP and acing the angles on the first try; that would be some freaky ****. If you're using something like Kaplan, be fore-warned that the overwhelming consensus is that the Kaplan blue book is way too easy and for their online tests, only Keyholes, TFE, and Pattern folding were useful for me (but very useful).
 
Wow. Thanks for the super fast response. Your response seriously helps so much. I'll definitely go over Schaums and most likely Cliffs too (for general review). As much as I want to read all of Campbells, I think that might be overkill. I'll definitely use that book for reference, however. Also, DATQVault sounds like a great idea. Will get on that ASAP, along with the flashcards program.

And sorry for the misunderstanding. I actually haven't done any of the ANGLE problems yet in CDP (totally my bad for writing that). I meant TFE angles😀, hole punching, pattern folding, cube counting. You are right, however. I heard they were hard as heck to distinguish a lot of times. I heard the "slope" or "bike hill" technique works wonders, though. We will see! Like I said, I haven't started serious-studying yet.

Anyways, thanks again and good luck applying. Wait, are you applying for this year's cycle (seems a tad bit late, but I'm sure that isn't a huge concern for you with your stats) or next year?
 
Folding(along with TFE) is the toughest section for me. What do you mean by only visualizing in 2d, if you could elaborate please.

Like I can rotate the shape until I get the main pattern I want and sometimes I can say oh the shaded region isn't touching the unshaded region so it wont even when you fold it. But beyond I have to fold it in 3d which would probably explain why i get so many of them wrong in topscore.
 
I dont know if anyone has used it, but I did in the past for my entry level Bio classes, Campbell's online resources? Campbell has quizzes/tests(each 40+ questions for each of the 50 chapters)/overviews/diagrams etc.. all online. I remember my teacher got a lot of questions from the practice tests. If I recall correctly, the wording is most similar to the DAT too.
 
@Froggbuster: how was Datqvault compared to real BIO..... Was the material more extensive and questions trickier or a little less extensive but trickier

Thanks guys

Do the online resources require an access key?

I'm applying this year, schools received my app a week ago and the schools are just waiting on my DAT score. It's not early but I don't think it's that late either.

It's tough to explain over the Internet like this, so it's probably better to do an example. Can you post a pic of a pattern folding problem that you're having trouble with? PrintScrn, save to Paint, and upload the image to here.

@Froggbuster: how was Datqvault compared to real BIO..... Was the material more extensive and questions trickier or a little less extensive but trickier

The scope of the subjects covered = the most valuable part of DATQVault. It covers like 90% of the main points you need to know and makes you aware of topics you need to work on. As for the trickiness of questions, DATQVault has some tricky ones but the majority are pretty straight-forward. The real DAT WILL have tough ones you need to reason thru, so know your concepts thoroughly and well, don't just memorize everything.
 
This one is from topscore. after looking over it i think i understand based on the dot placement. The answer is A but this problem trips me up because of the two opposite diagonals next to each other.

Amazing job man! You totally nailed that test. I hope you get into your dream school because you totally deserve to!

Now the next probationary status member's dat results to wait for is LetsGotoDSchool! 😀


I'm expecting him to do very well too.

Talk about the pressure haha.

You're right about needing to do well on Angles in order to score high on PAT. Lately I've been getting 15/15 on every other section and my thoughts were that would compensate for angles in which I can only get about half correct. So I'm gonna spend the next two weeks training my eye.
 
Congrats! Excellent scores and exceptional breakdown!

I had the ethic RC question also. Agree 100% on S&D with that.
 
Did you frame your score report sheet yet? I did.
I don't know where it is actually, lol. My mom photocopied it a couple of times and keeps one on her desk and brought one to the office though.

Guess my race.

BTW I added up my scores a week or so ago and found my AA was 24.4. -_- So close to the promised land, yet so far.
 
Haha, my dad was like oh this looks good...What is this perceptual ability part? IT DOESN'T MATTER RIGHT?!!

Now back to evacuating...ugh
 
You and me both..
I've given up on understanding how the percentiles work 😕

I was confused by this a lot too in the beginning, but a lot of help from these forums has helped me to understand how it works (I believe).

The DAT comes in many versions.
Over time, students have excelled more on some versions than others. This is how they receive the percentages.

Thus, for an "easier" exam, it would require you to get MORE correct answers for a designated section in order to receive the same score (25, let's say) vs. a "harder" test which wouldn't require you to get as many correct answers, for that same 25 score.

It ends up being really fair, and that's why Dental Schools don't need to see percentiles because essentially percentiles only compare you to how other students did on THAT test version; while the universal score of 1-30 is a designation that spans every test version and compares students universally, which is what Dental Schools do.

So, while a 25 on one test may be 95th percentile, but only 92nd percentile on another, either way you still earned that 25 and it is equatable to the 25 someone else got on a different version.

Hope this helped. Correct me if I'm wrong somebody.

This is all from the DAT User Manual.

1. Not all question you answered on the DAT will be marked. There are experimental questions that will be asked, and are eligible to enter into pool of marked questions on future tests. For example, only 75 out of the 90 questions on the PAT is marked. The 15 will be assessed on the difficulty, judging by how many people get it right or wrong. A difficulty parameter is assigned to every question, and questions that have difficulty parameters of 0.4 to 0.7 will be used as future test questions, with questions closer to the 0.7 being preferred.

2. So from these questions, a test is constructed, and scored. The sum of the difficulty parameters is used to gauged the difficulty of the test. There are multiple versions of the test, and if you have a certain version, then ALL of the questions, from the natural sciences to QR, will be the same.

3. You get a raw score from your performance on the DAT. The percentiles are relative to test takers who took the exact same test as you and received the same raw score.

4. Your individual score for each section is then standardized. Let's use Biology as an example. If person A got 37/40 on Biology, they would get a higher percentile than someone who took test B and got 35/40. But what if the sum of the difficulty parameter on test B is higher, should person B be punished for getting a harder test? of course not. When they do the standardization, the numbers will be closer together.

That's why percentiles are there, just to give a measuring stick on how you performed on that particular test. Standardizing will adjust for test difficulty, giving adcoms numbers so they can compare applicants who took different versions of the test.
