practice test score went down by 60??

I think it was mostly because I didn't sleep well last night. I knew I shouldn't have taken a test today as I was pretty certain my score would be demoralizing...

I went from 1370 to 1310, with almost all the points lost being in math. I'm (re)taking the real test in October, so there's still time to improve, right???? I am kind of freaking out.

I took it in June for the first time and got 1250, so at least I've improved from that but not nearly enough!!! I practice 6 hours a week, is that enough? Too much? Is it just burn out? I honestly kind of gave up on the last few math questions because I was so tired. I hope it was all just fatigue.
