Thanks everyone!! I misposted my BIO score which was an 18.
For the RC: I didn't put much effort into it before the test but the way I approached was to first read the passage then answer all the questions that were straightforward and able to find in the passage and saved my time in the end for the more complex questions.
I bought the KSF review which was OK but had lots of mistakes in it especially in the PAT part. For bio, I used the 6th edition Cambell book. For the gen. chem or and organic chem. I studied my class notes and I thought Barron's DAT book was very helpful for giving a quick, dirty lowdown in the general and organic chemistry.
