I only have to get 1000 GRE® CAT, but I am still so nervous - HELP!

[Blumuun]

I take the GRE CAT on Thursday--that's two days, and i am flipping out.

i only have to get 1000, but am horrible at math.

i did get an 1160 on one of the official CAT practice tests from ETS powerprep but obviously it didn't grade my writing.

i have been steadily learning and doing practice with the vocab, and am not really worried about that, i have a large vocabulary. but i am so worried that the practice tests will not be an indicator or that i will psych myself out on test day.

i am going to practice more tonight and tomorrow, but how likely is it that i will receive 1000 on my GRE?

thanks for any advice,
-C
