from your question I understand that you are looking for a school to learn English as a second language? If so, I can suggest Collin County Community College. They have classes there. Also, check with the city of McKinney. Most towns give classes as a second language at a very cheap price.
What is your native language, may be I can send you links with instructions in that language.
