Getting my MMR as an adult... what to expect for side effects?

Basically, my parents skipped out on giving me certain vaccines so I'm having to go through the process of getting some as an adult. I had one dose of MMR as a kid I'm pretty sure but then never got the second. Most of the side effects online are more for young kids though, so is there anything different I should expect as an adult? (In terms of like typical fever/muscle ache, level of severity). I don't typically have any reactions to flu/covid/any other shots besides a sore arm.

My clinic has a booking open for me to get my MMR on Monday but I have most of my final exams in the two weeks directly after. Basically, will I still feel well enough to study and write exams? Is it easy enough to just take an advil or will I be miserable?
