## Secrets To Scoring High in JAMB Mathematics

Most times, JAMB candidates feel that mathematics is the most difficult subject to pass in UTME. This is because they are still ignorant of the key secrets to answering the question correctly.

On the other hands, they are still other candidates who find mathematics very interesting, thereby scoring very high JAMB. The application of the basic secrets that I am going to share with you here will make you to join the league of those that score 100% in JAMB mathematics examination.

The JAMB Mathematics Syllable is a specially adopted compass to guide every candidate that will be writing Mathematics in the 2023 JAMB Examination. With the syllable, you cannot get confused on which area to concentrate while reading for the examination.

It is important to note that first and the key secret to scoring high JAMB Mathematics and any other subjects is to streamline your reading to those areas that have been stipulated by the Joint Admission and Matriculation Board according the syllable.

Although, JAMB usually recommends some textbooks which you are expected to focus more on, you still have to explore more ideas from different scholars.

### 3. Practice More Exercises

As you read your mathematics textbooks, be reminded that Mathematics is not like other subjects like Biology and Chemistry that you can just read line by line and drop after.

It is required that you must constantly practice all that you are reading in form of exercise. This practice will test whether you are really understanding what you are reading or not.

This is also the most important secret to gaining confidence in solving JAMB mathematics questions. Even if you practice the exercises and did not get them correctly, continuous trial will make you stronger, better and smarter in tackling any kind of questions.

### 4. Embrace the Use of Past Questions

Another important secret to getting a good score in JAMB Mathematics is the use of past questions. It is quite synonymous to the aforementioned point, Practice More Exercises, as they both get the candidate better equipped for the main examination.

More to the advantages of using past questions to study during the preparation JAMB Mathematics examination is that candidate will be able to identify any questions that are repeated from the previous years. In such case, the questions automatically become part of bonuses to the candidate.

With the above secrets well put into practice, you are definitely going get good score in the JAMB mathematics.
