Do I need to take the recommended course in order to gain more ad opportunity?

Being an international student reduces the probability of acceptance at all of the reach schools on your list. Are all of the schools on your list affordable? Is U Houston affordable? As an international student applying to public schools as a transfer you are unlikely to get any merit aid/discount.

Posters here can help you if you want more suggestions, but do tell us your budget. Thoughts @MYOS1634?
