SAT prep for international students

Hi I am international students in usa. I have been preparing for SAT for 5 weeks for 30-40 hours every week. My reading-writing score was 310, math 500.. Now i just improved about 100 points.. I can't improve..Especially reading writing..how should i study.. Reading writing passages is difficult for me..it takes time understand long difficult sentences. And i encounter a lot of new words. Should i study all of them.

I'd recommend consulting the strategies in these articles for improving your scores on the Reading and Writing sections of the SAT. You can also check out this article on how to prepare for the SAT as an ESL/bilingual student to see some more options for prep methods you may not have tried yet.
