I am sorry - if I knew how to improve 100 points in one week, I would be a rich man. I hope it is a glitch.

For math, You can take a few of the GMAT Club Math tests - one is free. you can get others, you may need just a few - they are $12-13 each.

I would recommend focusing on reviewing your weaknesses, basics, and hone in on careless mistakes - do you know why you scored 36 on Quant in GMAT Prep? That's the question you want to answer.
