The IEI offers six levels of English language instruction. Students can enter the program at any level, 1 through 6, depending on their English language proficiency. Also, they can move at any rate through these levels, or even skip levels, depending on how their English proficiency develops. It should be noted that students who do not pass a level will have to repeat that level. As a result, if students do not pass one or more levels, it will take them longer to finish, and this fact may affect whether their scholarships continue (if they are scholarship students). For example, if a student places into level 3 and passes all his courses, he can finish the program in 4 sessions, or 2 semesters. However, if a student places into level 1, does not skip a level and does not fail, the student will need to study in the IEI for a year and a half. Generally, it takes one to two years to complete IEI studies. Serious and hard-working students who participate fully in class work and the broader university community improve their English language proficiency quickly.
