It’s a good point because super-scoring is typically optional at schools that don’t require the reporting of all tests taken, and really is intended to help students put their best foot forward. Also, the schools are happy to combine high section scores to help their stats.
As for @Cloudybay23’s question, if an applicant has achieved a score demonstrating improved capability in a section, it is hard to see how disclosing a lower score in the same section from a prior sitting would be worse than giving up the super score bump. The question is, where would the student then land in the school’s test score range, and is this actually a choice between super-scoring or going TO (if available)?
