We understand that some schools are yet to officially released the names of admitted students for the 2016/2017 academic session.
In meeting up with the November 30th deadline earlier giving by JAMB for all admission process to be concluded, many school have already sent the names of candidates considered for admission to JAMB for confirmation and approval which JAMB is expected to upload on its portal.
Observation shows that JAMB has uploaded the list of students admitted into schools like OAU, FUNAAB, KSU etc despite the fact that these schools are yet to officially announce their admission lists for 2016/2017.
This implies that even if your school of choice has not officially announced any admission list for 2016/2017 academic session, you can actually confirm your admission status on JAMB website.
I understand that some candidates are skeptical as to the authenticity of the admission giving by JAMB. For the records, if your admission status on JAMB website reads "ADMITTED", it is only because you have been offered provisional admission into the school indicated by JAMB even though the school is yet to officially announce its list of admitted students.
