I wrote the TOEFEL test, but I want to know how important it is in order to get into an American university?
A good TOEFL score can help you get into a good university, but some community colleges will still accept your application without it.
Several institutions accept scores from alternative exams such as the IELTS, DET, and other self-administered tests. Inquire about this in great detail with the universities to which you are applying.
Do check with the university your are applying to get more insights on this.
