Tuition costs vary by university and the number of credits taken. You will not likely pay more than USD6,000-7,000 per semester, though additional fees will be charged for room and board (even if you choose to live off-campus, you will still have to pay rent on a flat and have money for food and other essentials).
Check with the university to which you are applying and your home university (if you are currently a student) to see whether you are eligible for any financial aid packages or academic stipends, especially those aimed to encourage cultural exchange with the Middle East.
Accommodation
Most universities provide some form of student housing. This may or may not appeal to you, depending on your social habits. While the legal drinking age in Egypt is technically 21, alcohol is strictly forbidden in many dorm complexes. Similarly, most are militantly segregated by gender.
Fortunately, if university housing is not your cup of tea you will have no problem finding an affordable flat in Egypt. For more information, see our section on housing.
