Does an admissions committee check if a student retook a class Many schools around me (in asia) allow a student to retake any class, regardless of grade, and replace it on their transcript.  Is it normal for an admissions committee to query if the school an applicant is from allows this, or is it not thought of at all?
If the class shows up twice on your transcript, the committee will know you retook it.  But they probably won't care.

If it doesn't, it won't even occur to them to ask.  (At least in my experience.)
