The test is definitely an endurance. I found when I took my practice test, the essays got me "warmed up", because while they matter, they don't as much as the other two sections. All I'd suggest is to take some more practice exams, and make sure you're well rested. Turn off all distractions (shut your room door, leave the music off, etc). During the break, go to the bathroom, get some water just like you will on test day.

As for not wanting to understand, you just got to have ruthless focus on finding the right answer and moving on. When I find myself get distracted by "hm, this is an interesting article" Or "this is boring", I interrupt that thought and ask my mind "Ok, what is the author saying here?"

As for improving your vocabularly, get yourself the Manhattan Guide to Sentence Correction. I'm a native speaker, but it's been teaching me a lot about the formal rules of English, both confirming things my ear knew, and teaching me new things.

The GMAT really doesn't test vocabulary, and it looks like you're OK with that, because you're reading US articles and your post really didn't use wrong words. I think your weakness lies more in the grammar, which can be improved with the Manhattan Guide.

Good luck!

First of all, you are absolutely right that a lot of practice and concentration is the key point in my situation. I'll work harder...

In addition, I'am agree with you about Manhattan SC! It's really great book! I read it 5 or more times

Thanks for your advice!
