<p>What’s the first math class you would take? Most important for Calculus are limits (some schools cover limits in pre-calc, but they will be introduced in calculus again if you have not seen them before) and elementary functions (polynomials, exponential and logarithmic functions, trig functions and trig identities). If you already had calculus in high school and would take a more advanced class or statistics, I would recommend you enjoy the break!</p>
