Do colleges look at cumulative GPA from junior year or senior year?
It depends on when you apply…an Early Decision applicant might not have anything but a GPA from junior year.
Most likely you will have some senior year grades when you apply.
Also, ask your guidance counselor what your school does…you could also look it up on your town’s Board of Education and search on GPA Calculation.
For example, ours says:
Beginning with the graduating class of 2012, an additional rank will be computed
at the end of the first and second marking periods for all students in their senior year.
GPA will be updated at the end of each marking period of a student’s junior year and
through the first three marking periods of the student’s senior year.
