Thanks everyone's suggestions. I will re-take TOEFL in early Dec. I know every top B-school require TOEFL score above 250. Only because I already took TOEFL 3 times and tired to take it again when I finished TOEFL this time. It's a long way to go. Hope everyone can apply successfully.
Take it easy! ETS treats you really nicely if you have no fear of them. That's my experience. The only time I was relaxed, I got a not bad score. Listening is difficult and reading is tricky. You will be fine!
can I use the sub score in the different tests? because in one test I got listening 61, but grammer 57. Another part got listen 57, but grammer 65. It is so tricky...
