I'm disabled and have problem at my college.?

You probably do need to take these English cles, but you should be able to ask to have them adapted for your needs. For example, I have a friend who is Deaf, and he was required to take foreign language in school, so he worked with the teacher so he could learn the language without having to speak it aloud. Since you have a speech disability, as well as a hearing impairment, I wonder if you can do something similar? Because you do need to improve your English in order to do well in college - so you need to improve your understanding and writing of English; but your speech - is that something that the teacher can not require from you? Talk to your teacher, talk to the disabilities services office on campus, and see what they can work out with you.
