<p>Considering many/most (top) colleges really recommend taking 4 years of math up to Calculus, it’s not a bad idea to take it to really gain a threshold into college level math.</p>
<p>If you’re struggling with pre-calculus and basic algebra stuff (i.e. quadratics), I can only imagine calculus is going to be hell. But I’d suggest keep trying, and go back and master your basics all summer. If you feel confident in your pre-calc skills, go ahead and shoot for AP Calc. At worst, drop out into pre-calc which should be a breeze at that point.</p>
<p>Bottom line: keep working and try for Ap Calc.</p>
