Yep.

At my university, after the usual calculus/diff eq/lin alg sequence everyone in STEM takes, we had “intro to advanced mathematics” that was proof based, taught in the spring, and a pre-req for everything higher level (abstract algebra, real analysis, etc). Most math programs have a similar “first proofs” class as their “weed out” class.

In that case the weed-out course is _after_ the calculus/diff eq/lin alg sequence then, not the intro math course.
