JAMB Physics Questions 2020 | Check Physics Likely Questions to Come out.
The Joint Admissions and Matriculations Board (JAMB) is a Nigerian entrance examination board for tertiary-level institutions. The board conducts entrance examinations for prospective undergraduates into Nigerian universities.
One of the reasons why students find physics very difficult is that cramming the formula alone will not help. You need to understand how the formula works and whether it is applicable to the questions asked.
All candidate need to understand that Physics requires accurate thinking and focus. For example, if a question is asked that a car starts from rest, it simply means that the initial velocity equals zero (U=0). You don’t have to be given the initial velocity in the question. Just apply the appropriate equation of motion and you are home and dry. Now when a car comes to rest, what will be equal to zero? certainly the final velocity.
Now, if you have ever wondered how to get Jamb past questions and answers in Physics for free, this article is for you. I have made the Jamb Physics past questions available for download.
Before I give you the link to download the Jamb Physics past questions, let me quickly introduce you to what to expect in the Jamb Physics this year…
