<p>My friends say that you don’t need to remember almost anything about Calc I when taking Calc II. Is this true? I ask this because I have now decided to take Calculus II (because of changing major to Computer Science) after passing my Calculus I AP exam 1 and a half years ago and I don’t remember anything.</p>
<p>If you learned your Calculus I material even moderately well, you can pick up the concepts very quickly in Calculus II. As long as you have done it at least once before, then relearning the material on the fly shouldn’t be a problem. </p>
<p>Personally, I would not worry about it at all.</p>
<p>It’s possible, yeah. Calc II deals more with Integration whereas Calc I was almost exclusively Differentiation etc.</p>
<p>Just know the basics and you should be fine. KNOW how to integrate. this is your main conern</p>
