Do you know any US university which does not require GMAT/GRE and TOEFL to master courses, and which is cheap?

Answer 1

Well, it's easy to find one that's cheap. Buckle down and take those tests, get good scores and get a teaching, lab or research assistantship, then you won't be paying anything (assuming you're a full-time student); they'll pay you instead (albeit not much). Of course this probably doesn't apply to business school if that's what you're looking at--they probably don't need grad students to teach or do research.

Depending on what your native language is, you may be able to get a teaching assistantship teaching your language if there aren't assistantships in your actual field of study. You'd have to contact faculty in the appropriate department to find that out. Spanish can almost always use teachers and in many cases, not all their grad instructors are Spanish majors. There may also be openings in languages that don't offer language/lit majors but that offer a few classes in the language whenever they can find someone to teach it.

For now, register for those exams and start preparing for them, and look at some university websites for more information about programs that interest you, look at their application and admissions requirements, etc.

Answer 2

No, I don't know of any. Good luck!
