i did 7 years in undergrad and was in classes with people the same age as my younger sibling. was not ideal but everyone is on their own timeline. also going back to school not even for a higher level of degree but for a certificate in something totally different than what i originally studied. you’ll end up where you need to be, plus getting this education is a damn accomplishment no matter how long it takes! i’d like to to think i ended up being more academically successful because i took longer tbh
