Well, this year is test-optional, so the SSAT will either help you or not benefit you at all. Typically, SSATs are one of the first things the AOs will see, and I’ve heard that some schools immediately reject you if they don’t like your SSAT score. However, a 2178 should be fine as long as other stats are good. I’ve seen PLENTY of people with 99th percentiles get rejected so don’t worry : )
