My wicked sick PAT tutorial

SDN Members don't see this ad. (About Ads)

are these from achiever or sumthin?
these same alot harder than CRACK

yeah achiever----it butchered me in PAT. ANy help would be great plzz

Anybody correct me if i'm wrong on this but here goes:



The way you can find the answer is mainly from the top view. For the right side you know it's slanted because the slant forms a rectangle whereas a vertical cut would not lead to a rectangle. I drew a 3D back view to let you see what I mean.

Same goes for the top left box. If the answer were D, the top view would look like the picture I put up above D.

As for A vs. B, the only difference is squares vs. circles and from what I can tell, the square's length is bigger than the corresponding lengths in the top and end views, so the protrusions must be circular/cylindrical.



For this one I've highlighted the lengths of each section that you should be able to see in the end view. You have a piece that is short, followed by a middle sized piece, then a long piece. Choosing between C and D, you can see why C doesn't work because the order goes middle, short, long instead.

After eliminating A and C, D vs B you can distinguish based on the dotted lines.

Let me know if that doesn't make sense

Thank You---the second one makes perfect sense to me

The first one I completely understood now that you explained it but I hope I can apply this diagonal line thing on real DAT- DIagonal lines really throw me off---i cant picture them.

But andyways Thank you so much for your help

2th, I think I now have a crush on you. You're awesome.

Hey Justin!

Thank you sooooo much for your detailed reply. This helps a lot! I used to freak out when I see questions dealing with circles!

I think I know what you were trying to show (and what you're asking), but I'm going to take the "arrows" out of my verbiage because I think I might be able to explain this better without that term.

If you look at Answer "C"...where the sides of the circle are at their widest...those will appear as solid vertical lines in the Top view. Where the sides of the circle come down and touch the base,...those lines will be dashed vertical lines from the Top view because from that angle the circle itself is obstructing your ability to view that junction directly.

Forget about the "roundness" of that circle in "C". They just throw in that extra dimension to mess with your head and get you to waste time contemplating how the roundness figures into the whole picture. Remember, from the Top view, you have no depth perception (aside from implied depth perception due to the dashed vs. solid line rules). So, even though looking at Answer "C" you see that the circle has depth in the horizontal plane (above it's midline plane...as it goes from 9 o'clock up to 12 o'clock and back down to 3 o'clock), when looking at the Top view of the given figure, all you see is a horizontal line. From the top view of the given figure, you have no way to know if that is in fact a straight (i.e.: flat/horizontal) line, or if from some other viewpoint it has height/depth.

So, when doing this particular problem, don't look at the roundness of the circle an let that throw you off. Look at the width of each of the shapes in all of the answers and also where the lines of those shapes are relative to the other lines in that same shape,....then look at the given figure and compare/contrast.

Just to drive the point home....look at Answer "C". Cut that circle in half, horizontally (so that you have the top portion which is from 9 o'clock up to 12 o'clock and back down to 3 o'clock). That is the widest part of that circle, right? Now look at the Top view. That second horizontal line form the bottom of the Top view is the exact same width line of that circle...just from the Top view.

The short-short of this particular problem....if you look at the widest part of the circle, it will tell you how wide the horizontal line (corresponding to the face of the circle is) in the Top view. It will also tell you that (based on the width of the circle), that from the Top view, the vertical lines that are second in from the sides will be solid (because these are the 9 o'clock and 3 o'clock sides of the circle, and hence the widest part of the circle), and therefore the "legs" of the circle (that come in under the circle and touch the base that the circle is resting on), will be the 3rd vertical (dashed) lines from the sides in the Top view.



Hope this helps.

All of these have been straight. How about curvy objects keyhole or TFE like some uneven top and bottom shape of spinning flying saucer or some kind of uneven half of hour glass? Or even curvy medallion. I got 2 objects similar to those in the last PAT. I think I got hung up on it and wasted minutes on it trying to logic it out.

first of all, thanks for all of your help. secondly i have about a month till my DAT and i was wondering what else to get from: destroyer, top score, crack dat pat, etc.

so far i have only used kaplan books, bio AP cliffs, barrons, and chemistry text book for chem review, i used examkrackers ochem mcat book for ochem, and pat not really much but the kaplan (i know its bad)

so preferably what would be my best one or two things to get to get a good review/practice problems and for good price---note that i cant afford everything. thanks.

i would like things to focus on pat and have real dat type test questions. thanks.

I have a question regarding CUBE COUNTING!!

Is there any need to determine the sides of every single cube, or it's a better time saver to only find out the ones they ask for. are there more than one question for one set of cubes???

Also, I read that some ppl prefer doing the 1,2,3,4,5 versus Top, middle bottom chart. Does that work well? I feel theres no need to write out what layer the cube is at....?? do you guys bother double checking the number of cubes in total and making sure you accounted for every cube...or too much time....

My problem is counting and keeping track of the cube on the computer...this section was the easiest for me when doing it on paper (the canadian version dat!) now that i need to write and take my eyes off the computer i lose my concentration in where i was counting at (my trick is to leave the mouse at where the cube i'm counting...but kinda slow..)

HOW MUCH TIME FOR EACH SECTION OF THE PAT???? THANKS!!

I found this kind of folding question very hard. Can anybody share your tricks?

thanks

find a method you like best. I usually dont check total cube.

Both B. But I am not here just for the answers. I need to know how do they work out in your mind. thanks

btw. How do you know it is b not e or d for key hole?

Hey, okay for the key hole its not D because its not even at the top. I can see why its not E because the shapes have a side difference.... Do you see what i'm saying?

hmmm, no tricks. gotta practice this shape until you know it like the back of your hand. this and the dices are a couple of the "easiest" hard paper folding questions

Originally Posted by hausee

B has that invisible part... wtf.

Other than elimination,there really are no "tricks". You can throw D out because the shaded regions in the unfolded template NEVER go corner to corner. C looks like it was drawn carelessly (the top square, I can't tell if the shaded region is corner to corner or not), but we'll keep it in the running for now. Next step is to look for a "two block repeat" or two reference squares. The top two squares in the unfolded template correspond to the bottom two squares in cubes B and C.

To eliminate A, look at its bottom two squares. The bottom left square (this is the one that is facing the viewer) in cube A corresponds to the bottom right square in the unfolded template. So the only way to get cube A is to have the top of that same square match up with the square directly above the corresponding one in the template. one quick look will tell you that's not the case.

Moving on to B and C, we have now established two "reference squares." The two reference squares in the folded cubes correspond to the top two square in the unfolded template. Looking at cube B and C, the only difference is the square on the top. Looking now at the unfolded template, one can see that the bottom left square is the one that folds to form that top square in the folded cubes. However, using a little common sense, you can see that the bottom let square in the unfolded template has its shaded portion pointing to the corner; a corner which is not adjacent to any other shaded lines. This is the case in B, and not C. Besides, the top square in C just looks plain silly.

Let me know if that helped.

That's really bad reasoning. You can't tell if the corner is actually adjacent to any other shaded line unless you fold it in your head or memorized how each square interacts in this type of shape. If C was drawn better, C and D could easily be correct choices. You can't tell that the bottom left corner is not next to any shaded sides unless you fold it in your head. The only way to discern between the two is to actually fold it out in your head, which is easy with these cube type questions. If you're having trouble, I suggest you get a piece of paper and cut this shape out, and spend 10 minutes memorizing how it folds so you can fold this type of shape in your head in less than 10 seconds.

You should get accustomed to it to the point that you know that the bottom left corner will touch the middle corner of the top two piece.

two more key hole. Please tell me how you figure it out, not just answer. thanks

I recently took the DAT a month ago and after practicing using CRACK DAT and Kaplan my score really really sucked! I'm trying to score at least a 20 next time around and this thread has been very helpful. However T/F/E remains to be the worst section for me. I'm averaging b/w 6-9 questions. Could anyone please help me translate these dashed and solid lines?

Maybe there is a simple explanation, but I just can't see it. I greatly appreciate any assistance!






I chose B, but the correct answer is A




I was between C or D..leaning more towards D. However, both were wrong. The answer is A.




I chose D, yet the answer is A.



I chose C, but the answer is D.

Wow I just found this website and spent five hours reading through a bunch of threads. This thread is awesome. Thanks everyone for contributing.

Hi it is very sad to say you might got the worst PAT material I every saw. For example. The end view suppose to look from right to left, however, your Qs is from left to right. See pic below. Also there are many wrong lines in your qs.

But to answer your QS.

1. C (dash line should be in the middle)
2. A
3. dont know what to say
4. same to 3, wrong 2nd line from right(front view), should be dash line.

hausee,

This seems very helpful, but what are your thoughts on line/events counting. ive been practicing with this, and it works most of the time, at least in eliminating half of the answer choices immediately which makes it easier to just compare whatever is different between the 2 answer choices.
the only concern is that I have never done the real DAT, but on Kaplan and CDP this seems to work like a charm. Do you think i can rely on counting line, at least for eliminating some answer choices on the real DAT?

I never use line counting so I have no comments about it. But I heard people saying it is not safe that rely on it for real DAT. Imaging 3D object is the key for this section. And becareful not fall into traps.

Thank you for letting me know about the errors. I know I need plenty of help with TFE. Do you (or anyone else) have any recommendations? I have CRACK DAT, yet I'm still averaging around 9/15 though.

THANK YOU sama!!!! i was averaging 18s on CDP until i read your tips last night and just finished my last CDP with a 21!!! thank you thank you!!

Hi!
Thanks for the post!
its was bit confusing but nice technique..
my dat is on nov 7th!
Goddddd this section really sucks.......
but ll practice with your technique..
Thanks again..

I'm between D and E on the first one. I think it could be D because if you look at the shape from the top, you would see a square, with a square hole in the middle of it (the "shelf" in the middle does not extend all the way into the walls, creating a continuous square if looked directly from above). Although E also makes sense..

For the second one, I think the answer is C, because if you look at the structure directly from the front, the front and the back shapes seem to line up, leaving us with the outline of C. A and B show these two not lining up, but it appears that they do. E is incorrect because an end view of the structure should show the middle rectangle as higher than the other two sandwiching it.

Hope this helps.. let me know if you see flaw in my logic

Hi sama !
I am from canada too and i have my Dat on Nov 7th.
I just have a question...
Do we need to take carving knife and scale or will they give us all the things needed for carving.
what about blank papers for calculations?
do they give us them or not?

I'm writing mine too! AH! I believe (don't quote me on this) that they give us everything... I would bring back ups just incase (ie pencils, erasers, paper, carving gear etc.) and worst case scenario you leave it with your bag.

GOOD LUCK!

I think the first one is E. In order for it to be D it would probably have to be more rectangular shaped.

I have a question, the answer in this image is C but can you tell me how can you tell that its not D, ie how can you tell that that line should be solid and not dotted??
thanks

It cannot be C. It's D, because the second dashed line from the top down on D is the far left edge where the 2 top and bottom slopes meet in the FRONT view. In order for it to be solid in C in END view, it implies there is some width changes where the solid would be which is not the case. Anyone agree?
