Waterloo Waitlisted - Rewrite OAT?

Hello,

I've been waitlisted but it doesn't seem likely that I'll get an offer. I tried emailing and calling the school to see if I should rewrite the OAT, but my question wasn't answered ...

Here are my scores:
QR: 330 80.0%
RC: 310 67.3%
BIOL: 340 77.7%
GC: 370 96.3%
OC: 400 100.0%
PHYS: 320 70.5%
TS: 360 92.1%
AA: 350 93.8%

Should I rewrite the OAT for the next cycle? I think I should since the only reason my score is at a 360/350 is because of chemistry ...

Thanks in advance!
