I've never done something like this before, I am applying for an internship in finance and they want me to take a timed assessment. It says no calculators are allowed (just pencil/paper) so I assume it's going to be heavy in Math. I only get to take it once though, so should I be brushing up on my Math skills beforehand? It's been a while since I took calculus, and though I got A's I feel like I have forgotten most of it. Anyone know what these are like?
