Take international exam may be dolinguo is the easiest and try to score above 120 . For sure u find a schoolarship by the score + try to get clube participation certificates from your school . Then go to Google and search university . Learn how to use common app then apply by ur self if the universitys don't acceptance the common app use the email or sth which is stated in their website . Now days all peoples becoming an agent (edu consultancy agent ) If u're not interested on ur self application try to check agency but I don't recommend any agency specially ethio airs is the worst and there will be some scammer agents. The truth is that every agency have some one that they send but bot all applied by the agency are not out.
