This article is for those who want to participate in the 2022/2023 Joint Admission Matriculation Board(JAMB) CBT examinations? It is important to note that practice makes perfect hence the need for this article. If you are going to be writing Maths in this year’s JAMB examinations then read this post extensively.

Mathematics is one the compulsory courses for those choosing a core science or core engineering course. One of the secrets to scoring high in JAMB is to practice with past questions before the main examination. Most of the questions asked are questions that do not require complex calculations and this is because the calculator is not scientific.

The Jamb examination has finally been concluded and those who would be writing the 2023 Jamb can now start practicing with the questions outlined below. Visit this page from time to time because we would update it with fresh questions before the next examination commences.
