Should I retake?

I want to apply to UNC, UMich, Purdue, Illinois, Notre Dame, but my top school is UMich.
I got a 1350 without studying really in December but with 6/4/6 essay scores, but then in March I studied more and I got a 1330 with 6/5/7 essay scores. Honestly, I think it was just a bad day or bad test.
Should I try studying more and retaking it in May to have better chances of admission? Help!!

BTW with superscoring I have a 1360.

Yea, retake. I got a 1510 with an 800 on Math and I’m retaking. There’s always room for improvement, especially in your case.

Ok thanks! @swagmoney00

what were your subscores ? and what are your weaknesses?

I would definitely retake it because the schools you are applying to are extremely competitive and that score would probably be too low.
