Improving english score

I am a junior with psat 1310 ,without any preparation, i have to improve my english score, is it better to take a english course at community college or go for English prep at princeton or magoosh ,which one is better please advice

I found magoosh pretty helpful (used it to study for my SAT and got a 1590, the only limitation is that there’s not too many reading/writing passages. I practiced a lot ran out in a month or so). and I’ve heard Princeton is good. It depends more on you though. Do you like self-studying/online practice or would you rather be taught in person?

It’s best to study SPECIFICALLY for the SAT English. I recommend Erica Meltzer’s books.
