It dependes on how long you will stay in the America before you take the tes ts. If just for 3 or 4 months, I doubt that you can improve your language abilit y substantially. But if more than 4 months, and you can make good use of the environment here , then there is no doubt that you can improve a lot. But it is still a hard job to learn language even here. Not easier than in C hina at all. It requires a lot of effort. The same effort you need in China. Just a personal advise.

it has more details, but the speed is not so fast. I took the test after 10 days arriving in US and got 25 but i think now i can get higher by sure.
