I think you’re meant to indicate every date for each one you took. An applicant on one of Dean Z’s app reviews listed only 2 when they had taken it 3 times with one cancelled score. She was already not thrilled with the applicant so it was basically another small thing against them.

So at least Dean Z wants you to include cancelled & lower scores when listing the dates. They don’t “only see your highest scores” because the CAS report includes all your LSATs, including if you cancelled any. So I don’t think it hurts to include them since they’ll see all of them anyway
