Admission Procedure In University of Abuja When There Was No Post-UTME

Following the recent scrapping of Post-UTME exas by the Federal Government, a lot of people have been asking how schools will screen students without the Post-UME exams, the purpose of this thread is to explain how that is done in University of Abuja which hasn't had a Post-UME exam in 3 years.
The first thing we need to realize is that an Exam is different from a Screening. In University Of Abuja, there are no forms, just a screening exercise. What does this involve?
Students who applied for the school in JAMB and have met requirements (minimum of 180 in JAMB and a Credit in Maths and English including subjects relevant to your course choice) will come for the screening with their credentials. At the screening, they present their results and answer a couple of questions (orally) based on your applied course (usually basic knowledge questions) after which they await the result of this exam.
This usually means getting admission from JAMB directly (first list)...and then 2 subsequent lists from the school.
Now, here's the catch. Getting the admission doesn't mean you're home free. Thousands are usually given this admission into 100 level, but they don't get an Admission letter from the school in their 100 level, because a second screening happens in 200 level.
If a student is unable to finish 100 level with a CGPA of 2.5 (3.5 in Medicine), he or she will be screened out of the school. Only those who achieve this mark remain in 200 level and are subsequently given the school's Admission letter.
Before the collection of this letter, it's safe to assume that you're not fully a University student until the end of this period of probation.
This screening usually leaves the school with at least half of the initially admitted students which is the needed population.
So, that's the University of Abuja model....I don't know how effective it will be in other schools
