I'm going to have a gap between math classes at some point. I can either take calc 1, then calc 2 the following semester, then have a semester gap with no math, and then calc 3. Or calc 1, no math gap, calc 2, calc 3. The reason im asking is because i will forget some information in the gaps, but for example if calc 1 has nothing to do with calc 2, then i would have my gap between that. So would it be better to have the gap between calc 1 and 2 or between 2 and 3?
