As you may know many universities this year like unizik, futo et.c didn't release any plain admission list rather names were being updated directly in JAMB Caps where students now go to check their admission status using their reg numbers.

Many errors have been encountered through this process as names were being skipped mistakenly in some cases by those uploading the names. Below is how you can check your name again in the updated upload in JAMB Portal if you think your score is above average but you have not been admitted. Recent uploads have been made expecially for Federal Universities.
