Did anyone else feel the physical science section was super hard? I still squeaked by, but my score definitely went down 2 points. The weird thing was I got a fine score on the bio.
oxeye said:I just finished AAMC 8 PS and it was definitely harder than 7 & 9 for me. I just barely got a 12, and I was well into the 13 range (pretty close to 14) on 7 & 9. So I dropped about 1.5-ish points.
Still a good score, but I had a horrible feeling after I finished it. I think I'm going to spend a lot of time reviewing that test and the topics associated with it.

IooI said:has anyone else been suffering form a downward trend? i think its because i havent studied a topic or opened a book in 3 weeks...all ive been doing since late march is taking practice tests and reviewing them.
Ugly Boy said:I'm not trying to sound like a jerk but honestly, what's so different about 8 than every other test? Sure there were roughly 5-6 reading comprehension questions but other than that, it's pretty standard, especially the G Chem. However, I did score the lowest in 8's PS - one point lower than average.
Whatsamatta U said:... the testes passage just killed me for some reason.
oxeye said:I took the BS section today and the testes passage killed me also. I missed 4 out of the 6 questions. One was a result of just not going back and really reading that part of the passage (tried to go by memory and that didn't work apparently), one I read too much into because the right answer just seemed too obvious - the other two I really was clueless about (because they required outside knowledge to answer).
But yeah - I missed more questions from that one passage than I did from the rest of the entire test. Ridiculous ...

Teerawit said:I'm sure you've read the solutions guide already, but here was my reasoning when I saw it:
-sperm cells/progenitors already have mitochondria, key principle (meiosis is energetically expensive)
-nurse cells = Sertoli cells, which nourish the sperm --> nutrients; proteins are nutrients; any secreted protein must go through the Golgi
Ugly Boy said:I got that question too. Passage wasn't so bad. Made me feel kind of macho.

sweetstuff25 said:i'm soooooooo frustrated with verbal reasoning. i feel like giving up!!! ek101 verbals felt so much more engaging versus aamc verbals. i hate seeing 6's in verbals. i hate it. ahhhhh. at least on ek i can score 8 and 9's but wtf aamc???

jota_jota said:Nurse cells secrete nutrients. Golgi is the cell packaging/modifying/trafficking center. Therefore, cells that secrete would be exprected to have lots of Golgi (and ER, but ER was not one of the choices.)
Shake_yabooties said:additionally, yes mitochondria provides energy via synthesizing ATP,
but if u think more carefully, no cells ever take up ATP from extracellular matrix. Thus ATP is energy for it's own. Then logically, what do our cells pick up for nutrients and nourishments? it's carbo, protein... etc.. remember..
golgi is associated with carboxylation and whatnot..
just adding to your explanation

I got 11 on AAMC 7 PS and 7 on AAMC 8 PS. My score dropped by 4 points. I am looking forward to AAMC 9 and see how I do. I thought for a moment about not taking the test at all.

you're right that in order to soften the water, you'd have to remove the calcium ions and make solid CaCO3 (rxn proceeding to the right). however, i understand that AAMC's explanation might seem a little convoluted. first, consider the solubility. as the rxn proceeds to the right, you are removing calcium ions and producing more of the precipate, solid CaCO3, which reduces its solubility. so right there, you can narrow down the answer choices to A and B. then, to figure out what's going on with pH, consider the behavior of bicarbonate ion. it's an amphoteric species, whose conjugate base is H2CO3, and whose conjugate acid is (CO3)2- (which combines with Ca2+ to form insoluble CaCO3). the pH of H2CO3 in sol'n is less (more acidic) than the pH of HCO3-, which is less (more acidic) than the pH of (CO3)-. thus, the pH of the reaction increases as you proceed to the right. i hope that helps.jsong812 said:Can anyone explain number 27 to me on the PS section? For some reason, I can't seem to understand their logic. I thought if you wanted to soften the water, one would have to remove the calcium ions and make the solid calcium carbonate. Because you are boiling the water, it shifts the reaction to the right thereby removing calcium ions and making more solid but you are using up bicarbonate (which is basic?) as well, so i figured the reaction should have a decreased pH? I understand that the increased temperature should decrease the solubility of carbon dioxide (which is acidic?) but is that effect stronger than using up a basic bicarbonate? thanks in advance.
