Hello!
First of all, to come out asking for help in such a situation requires so much courage. i had not been able to do that in the past. So hats off to you.
Here's what worked for me.
To forget about everything that has happened in the past and put all thoughts on the how glorious the future is gonna be. The enormity of the task simply grinds you to a halt. But a journey of 1000 miles begins with the first step. break down the complex and seemingly impossible task of 760 to simple and achievable set of smaller tasks. first step, find weakest part ( Sentence correction in my case). Attack it with all the vigor of a bull dog. then move on to the next, time and distance. and so on.After gaining sufficient confidence give a couple of practice tests. see where i'm making mistakes. go through second iteration. and finally take the test, knowing very well that you're gonna kick arse.

that is the key. to break down this tough task into a series of simple task.
I'm taking the exam around june 28th. lets share our progress.
We're here to help.
good luck.
