Maybe you could say you had a best test day experience? Tell adcoms that your test either froze multiple times, shut down, loud testing environment, locked out of the bathroom (some have keys - and this has actually happened before), etc. You can say you filed a testing center complaint and was very sure it would be accepted based on your chat with an AAMC representative, so you signed up for a new test thinking AAMC would void your score. However, AAMC takes time for these things, and at the end, the result is still unpredictable. So, after you took your second test, you could say AAMC decided to reject your testing center concern request? I don't know if this explanation is any better...everything still sounds like excuses to me, but it's a thought if you're looking for something to say

this might hide some of the bad judgement on your part...I'm sure everyone knows how difficult the AAMC can be sometimes so they
might believe you idk
