Is it bad if I never doubled up in lab, but manage to get all premed requirements done?
Another fear, myth or worry that has no factual basis
I believe so.To clarify, doubling up in labs means taking two different labs in the same semester, correct?
Do you know why these fears, myths, worries etc. originate in the first place? They all seem to assume that adcoms and schools are some scary, authoritarian entity that will look at each and every trivial (even nonsense) aspect in the application to find any and all reasons to reject them. That sounds like a complete waste of time if thousands of applications have to be reviewed.
My premed advisor told me it would look bad if I don't.
