# About JAMB CBT 2021 UTME

JAMB CBT is the newest way Joint Admission and Matriculation Board (JAMB) adopted to test her candidates. And one of the successes JAMB has made in the past few years is moving from paper based test to computer based test (CBT).

This new process has helped in reducing malpractice, saving time and cost-effective means of making UTME a fair playing ground for all candidates. In the time past, the rate of malpractice was high but this has reduced via the introduction of CBT.

However, many students haven’t been able to integrate well with JAMB CBT and this has led to failure or underperformance of many students. For any student to pass JAMB successfully, he/she must master the act of taking CBT which is quite different from paper based test. Mastering this act will enable you to pass JAMB successfully.

## Will JAMB Repeat Mathematics Questions in 2021 UTME

One of the frequent questions I do get from students on UTME is – Do JAMB repeat Mathematics questions? My response has always been – yes they do.

However, the way JAMB repeat questions in Maths is a little bit tricky, and sometimes they do it directly. All candidates who are writing UTME must know that JAMB secret lie in mastering past questions.

I do tell my students that one of the ways to unfold JAMB secret is to get like 7-12 years past questions in on Mathematics. You have to study the trend and pattern of the questions, its occurrences, and then extract areas/topics JAMB likes bringing out in each subject you are writing.

The above approach is what I referred to as a strategic reading pattern. I will give some examples of how JAMB repeats questions in the case below.

# How to pass JAMB successfully

Do you want to pass JAMB successfully? Then this article will reveal secret to pass JAMB successfully. JAMB CBT is the newest way Joint Admission and Matriculation Board (JAMB) adopted to test her candidates.

Here are the steps and how to pass JAMB CBT successfully:

**(1) Study well before you write UTME**

For JAMB CBT exams, Past questions are a must have, firstly, it serves as a means of making the students familiar with the way questions are being set and it properly conditions your mind on what to look out for when you are reading. Secondly, most times, past questions are reset in subsequent years, so it’s sort of a ‘legal expo’ since you have seen the questions prior to the exam.

Another thing is frequent study, once you keep your brain afresh by going through your notes and textbooks as a way of revising; you tend to remember things more

For the Use of English, build your diction and vocabulary as it will help you in the synonyms and antonyms section. How can you build your vocabulary? When you go through the past questions, have a dictionary, a book and a pen beside you. This will enable you check up a complex word, understand it’s context usage, and by writing it down, you won’t forget easily.

Some students do think about how to study for JAMB. The suggestion above has answered the question of how to study for JAMB. Past questions are guidelines that will navigate you through the way JAMB use to set their questions and those areas that do occur the most. I will advise that you pay attention to areas where JAMB like bringing out questions and you will see yourself scoring high. In addition, for students that will be writing Mathematics, pay close attention to differentiation, integration, binomial expansion, sequence, word problem, permutation and combination, probability, circle geometry, etc.

**(2) Relax and be calm**

Don’t allow the fear of the exam to get hold of you when you get into the testing hall. Fear may make you forget all you have read and eventually throw you off balance. Taking a deep breathe will help you dissipate the negative emotion.

**(3) Build a Time Budget**

At any given point during an exam, you should know the maximum number of minutes you have to spend on the current question before moving on to the next. This will definitely help you to pass JAMB.

Try to lay down very strict time limits for yourself on each question.” This strategy goes a long way toward avoiding time trouble; it keeps your attention focused and prevents you from spending too much time on any particular question. The key to maintaining this keen awareness is to build a time budget. First, take the time allotted for the exam and subtract ten minutes. Next, divide this amount by the number of questions. The result is how long you have to spend on each prompt. This provides a safety buffer. You want a few extra minutes available here and there to be able to double check your answers when you are finished.

Hint: Building a time budget will enhance your speed and accuracy. Don’t dwell too much on a question, there is no penalty if you guess and move on (No negative marking).

**(4) Proceed from Easy to Hard**

The most effective way to tackle an exam is to answer the easiest questions first, and this is exactly what you should do. Start with the most approachable questions before moving on to the difficult ones. Don’t worry if this has you skipping around all over the exam—in most cases the provided order is irrelevant.

It is also important to note that there is no particular order when writing JAMB CBT. You can start with any subject you find easy before you proceed to difficult ones.

Hint: For the science students, especially those doing calculation subjects like Mathematics, Physics and Chemistry, formulas are keys to solving any calculation. Once you see a question involving calculations, first bring out all the parameters given, then try to analyze the topic this question came from, after this you find out how the parameters are related, this is where the use of formulas comes in. By doing this chances of getting the right answer are higher

**(5) God factor**

This can’t be overemphasized. He is the only person that can dot your I’s and cross your T’s. And also silence other unforeseen factors that are beyond your power. Commit your study each day into His hands and ask Him for the grace to read, understand and retain.
