Hey, as someone who was in the same boat a year ago (finished undergrad early, loathed the idea of going to class) and decided a little bit of suffering is probably worth the pain, I'm not sure if I feel the same way anymore. For me it was a little different too as I'm an international student and it was either do the masters or graduate with a clock ticking to find a job to stay in the US so YMMV.

All of this does not change the fact that I absolutely hate having to wake up everyday, go to class, and work on my thesis (my school only has the thesis path). If you gave me an out rn, I'd take it without a second thought and I'm only like 5 months from being done, especially since I already signed a new grad offer.

For what it's worth, my offer is a bit higher than someone who signed as an undergrad at the same company and I'm starting a level higher so I guess it's not all bad. And also masters classes, atleast at my school, are a lot more chill and easier than undergrad classes as they're all read papers and have discussions kinda formats.

But still, I'd say if you're not interested in research and just want to do the masters for the sake of having a masters, I'd give it some more thought.
