I was wondering about how I am going to validate Calculus I and II with the precision I could have a year ago. Last year I took both Calculus AB and BC and got 5's for both on the AP exam. (5 on the BC, and a 5 for my AB sub-score) I plan to major in mathematics and understand all of the calculus concepts extremely well. Though I may understand the concepts very well, I have not retained the knowledge of my integration and differentiation tables. That goes along with all of the little rules about limits and the exact methods to calculating volumes. Does anyone have suggestions about preparing for the validation exam? Did anyone go through this? I would hate to take Calculus I and II, especially Calculus I, at the academy when I already have a grasp on the material.
