calc question?

<p>so im a little confused...</p>

<p>should 217 be taken before 216? </p>

<p>and what would be considered calc 4? i mean i assumed 216 since 215 is calc 3? sorry if this is a stupid question...i was just wondering if linear alg should be taken before diff eq.</p>

<p>and for a concentration in actuarial math (maybe), does anyone know how the sequence should turn out for these two classes (like which first)?</p>
