The Joint Admissions and Matriculation Board (JAMB) is a Nigerian entrance examination board for tertiary-level institutions.
The board conducts entrance examinations for prospective undergraduates into Nigerian universities and other tertiary institutions.
For one to pass Jamb exams you need to go through last past question which is most likely possible to contain all the questions that will be asked during the exams.
Atimes jamb do repeat their questions the reason to this i don’t know but 60 out of 100 question you will meet this 2018 JAMB exams are likely going to be a repeat of 2017 questions, so this tutorial is expected to be a helpful guide to prepare you for the exams ahead of the time stipulated.
Often times majority of students sitting for JAMB and other examination think that Jamb is hard, but it’s simple as ABC only if you know jamb tricks of confusing students yearly.
You don’t need to cheat before you can pass JAMB, come let me show you how to pass jamb using past questions and memorizing it to your advantage.
Schols.com.ng is here again to open your eyes and stop you from spending unnecessary money yearly.
