thanks for your responses.
The read comp was 2 sciences and one about stock market. for the first one,I skimmed through passage and wrote down the important words and then started working,but for the second and third one,I just went by questions and then found the answers in the passage and I still ended up with extra 8 minutes. ( english is my third language!!!
Organic was easy and kaplan stuff would do it ( although I don't know why I bombed it).
general chem with kaplan is good enough
math was easier than all the tests I had taken ,
for bio,you are better off, reading kaplan materials and taking DAT achiever.I took topscore,achiever and kaplan tests but DAT achiever section for developmental biology and ecology helped more.
let me know if you have more questions
