I recievied a NC in a remedial math class which wasn’t college level in community college.
If it shows up on the transcript (e.g. at Brown, NCs don’t appear on your transcript) then I assume it is treated as an F. Doesn’t matter that it was remedial, it was at a community college and therefore is a college class.
Yes community college classes are college level classes and AMCAS will count every credit earned from All colleges.
