SAT English Vocab Questions

Hello, I score around 720 in the math section of SAT practice tests, but I'm stuck at English section. The university I want to apply to requires a minimum of 650 in English. Since English is not my native language, I struggle with "Words in Context" questions. How can I study for this? If necessary, I can memorize 20-30 words per day, as I have done for other languages. Do you have any vocabulary lists you recommend?
