The UTME Examination Slip contains the crucial information about your Exam Venue, Date and Time.
As you all already know, JAMB has emphasized that there will be no re-scheduling of any candidate that misses his/her time. That means, the candidate who misses his/her Exam Date or Time will be marked absent.

There is no strict DEADLINE per-se, but it becomes a deadline for anyone, if your exam schedule falls on 13th May (the 1st Exam Day of 2017 UTME). This means that the deadline for each candidate to know his/her schedule is on the actual DATE & TIME of their exam.

Just imagine a candidate who finally reprints his Exam Slip on 13th May at 5:00PM, only to discover he was scheduled to write on 13th May at 7:00AM.

Since there is no other way to check your schedule alone (apart from the slip), Please ensure you all reprint your slips, or at least, know that your schedule DOES NOT fall on 13th May. ..
