<p>Hi, I signed up to take 5 AP tests this may. World History, Psych, and Lit. I'm cool with. I took/am taking the classes and I think I can get by with last minute reviews. The problem is Calculus AB and chemistry. I did not take classes for these. To give you some hints about how ignorant of those topics I am, I just kind of "studied"/nodded off my way through PR SAT chem book and scored lowly 670 on it. In calculus, I looked over PR prep book and I can just do some relatively simple derivatives (power rule, product rule, etc...). I want at least 4 on all of my tests. I am also willing to give up most of my available time for calc and chem. Am I complete helpless? How should I begin?</p>
<p>For Calc, go to iTunes U and download the Calc Courses from New Jersey Institute of Technology. They are video lectures and could certainly help. </p>
<p>There are a bunch of video lectures for introductory Chem on other colleges. </p>
<p>Then you can watch the material being taught.</p>
