Hi, I wanted to know from those people that scored about a 12-13 on the physical sciences how they did it. I have taken a few aamc exams and have repeatedy scored about 7's. If those of you who know how to get 13's can help me, I can at least get a 10 on the real thing. Thanks a lot. By the way, I know my chem and physics in and out, and I am finishing on time, its just that I don't have a good understanding of chem/physics laboratory techniques and have problems with understanding the detailed experiments found in many of the PS passages. I have tried not to be intimidated and just reason the passage out, but it has not worked as well as I hoped and I am still clueless about how to tackle these passages. Thanks again, for those who care to help, I appreciate this a lot.
