MCAT 2002 form BG

[Tweetie_bird]

****ty, just plain ****ty. What did y'all think about it? I can't believe how crappy that test was. All the stuff I studied....I might as well not have studied with the way the test was made. There would be no difference in scores.

Few quick things about specific questions:

1. The question about a gene increasing in frequency, and a chart was given. I believe the question was "when does the Heterozygote frequency increase most...." or something like that. I don't even remember what I picked, but what was the answer?

2. The thing about a parachute dropping something to a bunch of hikers on ground. The plane is going 100 m/s and is 500m above ground. What horizontal distance should they be away from the hikers to make sure that the package falls within their reach? I guessed--500m. What the hell was that?

3. Insulin most likely looks like--oxytocin, epinephrine, cortisol and something else. I picked Epi b/c I assumed it was a peptide hormone and works through second messenger much like Epi. Is that even right?

4. Why does something in water travel faster than in air? I picked the answer about how water molecules are closer together, and air molecules are further apart. Is that right?

5. The whole diarrhoea passage! EEK! Was that a bacteria or was it a virus?? I picked Parasitic Animal (b/c it lived in the villi of the intestines and replicated there..therefore, it was parasitic.) Also, the RNA transcript found in it....did it belong to the bacteria or a virus within it?? I picked the latter b/c when gene sequences were compared across different species of that bacteria, nothing was found in common. Therefore, it would have to be a virus. Plus, they said that cell wall antibiotics didn't work on it...which means resistance could be conferred upon the bacteria by the virus.
I hope I have this right.

Please...help me calm my fears! <img border="0" title="" alt="[Frown]" src="frown.gif" />

My logic for the previous example is this--if we throw a ball up in the air..it goes up with 10 m/s (for eg.) and decreases...till it reaches zero...and then comes down too, with increasing velocity. I got really confused with the question b/c I couldn't understand if they were asking for the graph once the terminal velocity has already reached, or starting with t=0, what the v and t graph looks like till it reaches terminal velocity.

I chose the choice where v increases fast initially and slowly reaches Vmax.

I wonder whether we reach 25% of all the questions yet. August takers who read this thread are going to thank God. Luckly, our scores aren't being scored agaisnt theirs.

 

[Papa Smurf]

I don't remember the question, but this is what a terminal velocity vs time curve would look like:
Notice that a=0 once you reach terminal velocity.

wooohoooo papa you rock! how did he do that??

 

[Medical123]

Does anyone remember a free standing question about forces? It was something like, you have 2 forces acting on an object. One is 11 N and the other is 7 N. Which one of these would not be a resultant force?

a) 12N
b) 2N
c) 18N
d0 4N

 

[uffda]

wouldn't it be 2N - the least you could get would be directly opposing the forces 180 degrees- and that would be 4N

[Papa Smurf]

Yeah, I put 2N. Same reasoning.

 

[Blitzkrieg]

I put 2N too..booyah!

 

[Tweetie_bird]

wow. I actually see a congruence in answers on the first question on form BG!! Way to go people!

My biological

This isn't cool. According to Kap's AAMC 4-6 scale:

15: perfect score
14: max 3 wrongs
13: max 7 wrongs
12: max 12 wrongs
11: max 16 wrongs
10: max 21 wrongs

Let's see, I got the followings wrong.

1. single-celled protozoan --- there goes 15
2. oxytocin as peptide hormone
3. last question of GYF passage, wild guess: assume wrong
4. 1.5x mRNA transcript (I put 1.0, possibly wrong) --- and there goes 14 heheh
5. HF and HI being most reactive (I think I put HF, but no idea, possibly wrong)

And there are so many more we haven't discussed about.

3 more wrongs, then I'm down to a 12, DOH. I hope the April curve will help a bit.

 

[Blitzkrieg]

was HF the wrong answer on that question? What was our final analysis?

 

[RT]

•••quote:•••Originally posted by Blitzkrieg:
•was HF the wrong answer on that question? What was our final analysis?•••••Heheh, I dun no. We left it hanging 'cause we weren't sure about the context of the question. Heheh. That's enough, no more wrongs heheheh Or we could make HF the right answer, hehe how does that sound ?

 

[Street Philosopher]

lol i'd be at 14-15 right now if everything else was right

 

[Alli Cat]

There are so many Q's that we all seem split 50/50 on (the HF HI one, the sheep giving birth in the morning one) and the sad part is that we'll never know what the right answer is.

I wish AAMC would put out the answers the day after. Or maybe after the scores come back... I kind of like this state of oblivion that I'm in right now. Before the scores come back, anyone can imagine that they scored a 40. Seeing the answers (and the ones you got wrong) would kind of shatter that happy oblivion.

•••quote:•••Originally posted by Street Philosopher:
•lol i'd be at 14-15 right now if everything else was right•••••HTH (Alli Cat) brought up a really good point. We all can imagine we did well. However, with your current 2-3 mistakes (aldehyde, AP threshold..), you might be able to pull a 14. But since we're only discussing ~25% of the test, it's likely we had even more mistakes, which would bring our score down even further. But congratulations anyhow.

 

[Street Philosopher]

Don't get me wrong I don't expect to get a 14 LOL
Just wishful thinking

BTW, have you been keeping score or something? hehe

 

[RT]

no, but i thought it takes a lot of guts to claim a possible 14-15, even with an if clause.

 

[Street Philosopher]

sorry. i just got carried away because so many of the things i was unsure about seems to be correct

AP threshold? for the muscle firing for epileptics?

 

[Tweetie_bird]

anybody realize that we are giong to go through this insanity for another 56 days? I feel icky when I realize what my score is going to be....I was scoring in the mid thirties on kaplan and AAMC and I would call myself lucky if I pulled a 24 this time. I can't even get rid of all my books from my room b/c I am afraid I will have to take it again. I hate this limbo we are in. <img border="0" alt="[Pity]" title="" src="graemlins/pity.gif" /> <img border="0" alt="[Pity]" title="" src="graemlins/pity.gif" />

I just hope the AAMC doesn't void all of your scores for having "memorized" the questions.

But hey, I've really enjoyed reading the posts here since I found out about this site Sunday... and wish I had known about this site before the MCAT.

my vote is for HI

 

[RT]

What we're doing here is similar to a group of "medical experts" :wink: discussing possible solutions to scientific problems. We haven't violated their rules, excuse' moi.

•••quote:•••"No portion of such materials may be retained by examinees. Pages or covers of test books are not to be torn out of or separated from the test books in any way. Additionally, test takers are not permitted to duplicate or record (by copying, photographing, memorizing, or any other means) any part of the MCAT."
(http://www.aamc.org/students/mcat/02mcatadmin.pdf)••••The only case that could be discussed is the matter of memorization which by itself is argumentative. Each of us has recalled a few questions and have brought them up here to seek further explanations for our personal curiosity. By no means do we intentionally memorize testing materials and thus jeoparize our privilege by discussing online rather than communicating orally.

Please don't say that.

 

[Papa Smurf]

All I have to say is the AAMC can go screw themselves!!! I don't give a **** about them or their rules after the crap they've put me through with their AMCAS app and this pathetic excuse for an exam called the MCAT. Notice how some of us may have gotten questions right even though our reasoning was off (Tweetie w/ the terminal velocity question and me w/ the CrO3) and then others missed questions coz they knew too much which complicated matter(Medical123 w/ the ketoacidosis, etc). I can't believe this exam is going to dictate whether or not I get to be a physician. It sucks!

 

[Mish550]

by the way, i talked to my physics prof and asked him about the pulley problem, and he said the work would be equal!

No wayyyyyyyyyy

The magnitude of work is equal, but there are certainly + and - values.

Aiiyyy... i'm not arguing anymore. If I were a bystander, I'd trust your physics prof probably more than my outdated knowledge.

Yayyy, Gooo to those of you who put "equal". I dun really know.

But thanks for the info.

Heheh... my choice is to wait to see whether I got more than 7 wrongs on that Physical section.

 

[Mish550]

I think we should all stop posting questions and answers to the MCAT now!! Enough is enough...we are letting this test consume too much of our lives! Let's move on to something else...otherwise we will just worry for the next 52 days!!

Fu@k aamc!

 

[Asclepius]

Out of curiosity, what were your essay topics? I wonder if they are standardized across the country.

 

[Street Philosopher]

IM me on AIM. my screen name is AMCASHATER

 

[MeGrowTall]

My essay topics were something like:
Progress can often complicate more than it simplifies.
Laws cannot change social values.

I think I did ok on the first one, but I slapped that second one silly.

 

[LittleMD]

Yup,

I'm pretty sure every form had the same two prompts for the writing samples. I wrote horribly for both of them,...c'est la vie!

I wonder what else caught me off guard...

Let's see, geometry of a molecule disregards nonbonding electrons, at least, I think this is what it says in AAMC 5/6.

[RT]

AAMC6: "geometry or shape of a molecule refers only to the positions of atoms, not electron pairs." It's a good thing that this question appears in AAMC6, otherwise I'd have been even more confused.

 

[Asclepius]

Right, but geometry certainly depends upon non-bonding electrons...

 

[Blitzkrieg]

•••quote:•••Originally posted by Asclepius:

[Asclepius]

Aaaargh! The posting has slowed down considerably and I'm still terribly anxious about the recent MCAT. The discussion was providing the commiseration that helps me to cope...
After 6-8 hours a day of study since January I'm having a hard time getting on with my life...perhaps I should initiate an MCAT post-traumatic stress disorder thread. <img border="0" alt="[Pity]" title="" src="graemlins/pity.gif" />

 

[Sm00th13]

I just wanted to say that it's great that you guys are going over the exam, but at this point, there's nothing you can do about incorrect answers, and your're just causing unnecessary stress. Just concentrate on doing a great job on your essay and application. Worse comes to worse just take it again in Aug. Even though I probably got wrong answers (e.g. on test CT), if I have to take it again, I will. But it's great that you guys are solving problems together.
Too bad we can't take the MCAT as a group, we probably get each individual to concentrate on one aspect of the MCAT. But here's hoping to those who took the April exam, get great results, I sure am.

 

[Street Philosopher]

Just in case there ever is a group MCAT, I got dibs on the writing section
