<p>When does math get useless? You learned quicker than I did lol!</p>
<p>Besides Linear Algebra, none of the other ones are necessary (linear algebra probably isn’t either, but I feel it is very fundamental). Of course, if your interested in any, give them a try!</p>
<p>I’ve heard numerical analysis isn’t very fun (not saying its hard, just not fun) and the rest are proof courses. UCBalumnus did a nice overview of the rest. </p>
<p>EDIT:
Adv Calc is typically thought of as a “bridge” to mathematics and number theory is usually considered the most fun fyi.</p>
