So, bad planning in my part: I just realized that NYU requires a literature/humanities testing score, and I didn’t take any SAT Subject test or AP exam in those subjects… am I just done for then? would it be too late for me to take an SAT subject test in January?
Many schools accept January scores for a January 1 deadline, but you should contact the admissions office. Another option would be to send SAT or ACT scores instead.
