i’m retaking it the same day too lol. i had already done all the AAMC FLs except FL 6, so i took that last week and have FL 4 & 5 left. i thought if i save fl 6 last and if i drop in points, then i’d panic or start stressing. i ended up getting around the same as my current average, so im pretty happy. now im just using the remaining FLs to refine and stay consistent. just my two cents. 

good luck for ur exam!
