i m gettin 80 - 85%...I think in the subject tests, there are some questions in the bio subj test for example that are very vague and from area that I would never imagine...so its really hard to get a perfect on them
sometimes I get like 14 wrong, i think this was for o chem exam 5...anyways i just keep redoing them...memorizing why the answer is what it is, hope this will help me on the real thing.
