Depending on the college/university you choose, your TESOL score may be much more important than your SAT/ACT verbal score. The colleges/universities have had applicants like you before so don't panic about this. Contact their international student offices.

I teach adult ESL. I like to recommend that my students read books in English that they have already read in their first language. You will know the plot and settings. The only things that will be new to you are specific vocabulary words (and you will know the meaning from the context), and peculiarities of English grammar and construction. Reading and writing truly are the keys.
All the best.
