Who is considered a junior in college? A full college schedule requires 15 credit hours per semester, 30 credits per scholastic year: thus a sophomore would have earned 60 credits and a student carrying credit hours in excess of 60 credit hours would be conisdered a junior in college. Mohamed Elhegery.
For undergraduate day students, freshman, sophomore, junior, and senior standing are determined by earned semester hours: 1  Freshman: Less than 32 SH. 2  Sophomore: At least 32 SH but less than 64 SH. 3  Junior: At least 64 SH but less than 96 SH.  Senior: At least 96 SH.
