Just concentrate on the question in front of you as if your life depended on it. Forget the one before it and the next one coming up and don't stress about the difficulty level of the one in front of you.

Make sure that you answer the right question! A great many GMAT questions will anticipate that, for example, you'll work the algebra to solve for x, but the question will require you to do something else with it (like solve for the 10 gallon capacity of the barrel and then subtract x to see how much of the barrel is empty).

You may just want to jot down a question mark (?) at the top of each page of your notes to remind yourself to double-check the question.

I've always maintained that the most common wrong answer to any question on the GMAT is the right answer to the wrong question. Be careful, and make sure that you get credit for all of the work you do correctly!

Best of luck tomorrow!!

So what score did you get?

well I got really nervous and blanked on the math so I actually asked the proctor if I should just cancel and he said just get it anyway, and it came out a 600, which I am happy with. I just finished my undergrad classes and had a 2 week window to get in as much studying as I could and I was shooting for a 550+. Now I just need to figure out where the heck to apply haha.
