Like any other ESL student from a non English country speaker of the Democratic Republic of Congo. Came with Swahili and other dialects languages started taking my ESL classes in Mark Keenum's class and became able to exit high school with all requirement in just few 2 years, I'm 100% recommending any student to him as a choice and will gain the same knowledge as I did . Mark likes what he does because learning was not easy. He was showing up to class earlier in the morning to make sure he helps all ESL student to learn and he was also staying after School as well. Was the first teacher being on time on our campus and stay later in order to help those who willing to learn. He personally taught me how to write,pronunciation, spelling,formulating a sentence, and I finally became able to pass my exit level of English test from Texas agency of Knowledge. I have no doubt for whoever willing to learn , having Mark is a good choice and will build you in all aspect.
