The management of JAMB had earlier announce
yesterday that the reprinting of JAMB exam slip shall
begin today, 6th of March 2018 while the main UTME is
to commence on Friday 9.
With regards to the above, here is how to get yours.
1. Email
The first step in getting your exam slip is to check your
email address since JAMB promised to send it to all
respective candidates email address.
If you didn't see it, don't panic... Jump to step two.
2. JAMB portal
The next step is to visit JAMB official portal for the
reprinting. Visit JAMB portal and you will see a link "print
UTME exam slip" , click on it and fill in the details in the
next page e.g your JAMB registration email and
password. Then click submit and your exam slip will
popup.
NOTE : if you didn't see yours, don't panic as it means it
is not yet ready but continue checking both your email
and JAMB portal and also you can get your reprint
through your phone or you visit a cafe.

Best wishes...
