Cheep up!

First, check the problem out. What's wrong with your test? Is the pace not so right? or is the math section not so good? or is the logic part not too tough?

Then, make a detailed plan. If you want to get a relatively high score, you might need to spend more time on the test preparation. And even when you write the test in Nov., it is still not too late for you to cath most second tier schools' first round application.

Finally, as long as you listenning section is good, the Toefl test is relatively easy. After you complete the GMAT, you can get a decent score on T with a few days preparation. Good luck.
