Does Clemson superscore the ACT?
This is from their website:
Request official SAT or ACT scores to be sent directly from the test agency. If you submit old SAT scores (from tests administered before March 2016), Clemson will convert the old SAT decision scores (critical reading / math / writing) into new SAT sections (evidence-based reading and writing / math). The overall total SAT score will then be derived by taking the highest of the evidence-based reading and writing / math scores. For your ACT scores, the best composite score will be taken
So no, it doesn’t look like they superscore.
