Studying abroad

I'm a sophomore and am interested in learning English. During my summer vacation, I'm gonna study abroad in Los Angeles. My English skills is still not good, so I wanna study hard. I haven't been to the USA, let alone Los Angeles. Please tell me the places in LA you recommend.

I'm a sophomore. I am interested in learning English. During summer vacation, I'm going to study abroad in Los Angeles. My English skills are still not good so I want to study hard. I haven't been to USA, nevermind Los Angeles! Please tell me the places in LA you recommend.

I've changed your 'wanna' and 'gonna' to the proper way. Although you used them correctly and they would be fine in a message to friends they are far from proper English and this is a learning site after all!

Other than that it's pretty good. I've offered some corrections different from Katie's just for variety, her's also make sense.
