I have been asking this question for ages. I personally think every topical has a different degree of difficulty (and its a very wide range) and its very difficult to put in an unbiased view. For example:
I did the biology topical: Endocrine systems test 1 and did really really well on it. I know my endocrine pretty well but felt the test was kinda easy (but maybe i just know my stuff?) but I thought it was pretty easy. In contrast I've done Physical sciences tests 1, 2, and 3. I GOT RAPED so hard it still hurts. I thought they were SUPER hard; however, I'm not that good in physics and maybe they just hit the specifics that i'm not the best in resulting in my dismal scores (test 19/31; test 2 14/27; test 3 (sorry cant find but it was around test 2's range).
Some physics topicals are really tough (at least for me) Electric circuits 8/17 =( Though I do need some help in that area and to contrast that translational motion test 1 11/16 (not soooo bad? but was this one really easy that I shouldn't have even gotten 5 wrong?)
Just to give a reference point I am getting 9's across the board when I take Princeton Diag's and AAMC. I'll occasionly get an 8. I also have taken the MCAT last August in which I got a 9 PS 8BS 9V =(.
IF YOU OR ANYONE HAS ANY INSIGHT ON THESE DAMN EXAMS TO KINDA GIVE ME A HEADS UP AS TO WHERE TO CONCENTRATE MY EFFORTS ON PLEASE LET ME KNOW. IF 5 WRONG IN TRANSLATIONAL MOTION IS PATHETIC than please tell me (sorry about the caps, been asking people for this info for a while now) if less than 50% right on electric circuits test 1 is still descent please let me in.
When I take a practice test I'll get between 1 - 4 questions in each area. So if i get 1 or 4 questions wrong, it may not be because I need help in that section the most (I may have gotten lucky in the electric circuits section and got 2 easy questions, both of which I got right) and I got some SUPER hard questions in translational motion which made me miss 4, but if I still need to spend more time on electric circuits, even though I got um all right (because they were easy). Its tough to judge whats easy or not unless you have a reference point (such as someone else) to judge from.
PLEASE anyone and everyone WRITE SOMETHING after you take ANY SORT OF practice questions (even if its from the science workbook) whether you think its hard/easy and if your normall good in that area it will help everyone including yourself. I'm hoping/need to get a 32 to not have to worr, but am realistically thinking I can only reach a 30, which will put me on the borderline of any school I apply to as my grades arent fantastic but they arent dismal either, if thats of any interest to anyone.
GOODLUCK TO ALL and remember, study your A$$ off, cause its worth it in the end. Keep your eyes on the prize. If possible study and do questions 8 - 10 hours a day, cause after the test is over, if you dont have to do it again and you dont have to worry (as much) about your future, you will be happier than any night/weekend/summer out drinking/partying.
Sucks to have to try so hard to do what you wanna do =..(, some say its not worth it, but if its worth it to you, like its worth it to me, you wont give up =T, hopefully.
