IMPORTANT NOTICE TO ALL 2023 JAMB UTME CANDIDATES

From our experience and expertise in the educational field, we wish to inform all 2023 JAMB UTME Candidates seeking for the 2023 JAMB Expo / Runz / Answers that the possibility of getting real and authentic answers are very slim or even not possible.

We are using this medium to notify all 2023 JAMB Candidates to beware of many Scam and Rogue websites who are out to defraud and lure gullible persons, most especially candidates sitting for the forthcoming 2023 Joint Admissions and Matriculation Board (JAMB) Unified Tertiary Matriculation Examination (UTME) scheduled to hold from Tuesday 24th April – Tuesday 2nd May, 2023, into believing that they can obtain authentic questions/ answers for the examination a day or two days to their respective examination date either using their JAMB REG Number or other details as it is IMPOSSIBLE.

Be informed that such scams are not new, as, over the years, old or fake examination question papers are usually circulated and sold by fraudsters, as authentic current ones, at ridiculous or give-away prices.

We want you to be aware that the claims on these rogue websites that authentic question papers or answers for JAMB examination can be procured in advance are completely false, for your information JAMB Exam is Computer Based (CBT) which makes it extremely difficult to have access to JAMB question bank without the notice of the examination board.
