A female or gender nonconforming humanities or even social science major stepping into an advanced math class that is a prerequisite for other things they might be interested in knows they're likely stepping into a hostile environment and have to be twice as good/confident as most of their classmates to prove themselves. The atmosphere can be a big problem.
