The beauty of some of these private institutions is the ease with which admission can easily be gotten. In this case, the student can be admitted without JAMB and WAEC only on one condition, being that upon getting to 300level or final year, the basic admission requirements like JAMB and WAEC/NECO must be ready for submission for clearance.
