I'm an electrical engineering grad student*, I expect to earn MS this semester and if I find a job will probably just take it. Unfortunately, my GPA is quite close to the cutoff for most workplaces (3.255)** so I'm considering taking what this school calls a "research problems course" for the sole purpose of shoring up my GPA a bit. I've calculated that it will make a difference of 0.1 GPA point. Problem is, it's at least $1k extra, probably more, so is it worth it? Or should I just count on doing well in the 2 classroom courses I'm taking? Clearly that didn't happen in the past. That course is basically just getting a grade for labwork, doesn't count toward the degree but helps GPA. I'm taking the thesis course, but it has no effect on GPA.
*(This may or may not affect the answer, but I also have a biology degree, chemistry background, and currently work in a biomedical engineering lab. Lots of different research experiences, but only 2 conferences, 1 conference paper.)
**Even last semester, when my GPA was higher, recruiters didn't seem too impressed.
