The Importance Of Mathematics In JEE Mains Exam

Are you focusing on getting admission to the top NITs or IITs? Then you must know for sure that to beat the high competition and get admission to top colleges it is mandatory to bring a good score. You need to be scholarly about all the three subjects the questions in the JEE exam are picked from, i.e, Physics, Chemistry, and Maths. All three subjects carry equal weightage and must be given equal attention right? But to your wonder, even after carrying the equal weightage, one subject is of utmost importance. That subject is mathematics as the JEE incorporates the high Importance of mathematics.

Importance of mathematics in the JEE exam

The subject Math is paramount and plays a crucial role in building the foundation of the other two subjects, i.e, Chemistry, and Physics. The importance of mathematics lies in the usage of formulas and equations in Physics and chemistry. Therefore a good grasp of Maths will automatically make the other two subjects easy for you. It is a well-known fact that the marks scored in math in JEE exam act as a tie-breaker thus telling the Importance of mathematics all the more.

JEE Main Maths

The best tips, tricks, and shortcuts for a good score in mathematics

1. Graphics made it easy

Knowing the importance of Mathematics in the JEE exam you should plan your preparation accordingly. Graphical analysis is considered one of the best techniques to get hold of Math the easy way. Draw a rough sketch of the graph and analyze it visually. Most challenging problems can be made easy with this technique. 

2. Hit and trial to rescue

One of the most fundamental tricks that provide a general solution to the problem.  This is done by allocating values to the variables and then evaluating which values give the desired results. More complex questions can be solved with this trick. 

3. Avoid extreme answers

Students are recommended to not go for extreme answers to questions that have numeric answers. Hence, stay away from maximum and minimum values because in any such case the answer can be anyone that lies in between.

4. Limit your options

Limit your options as much as possible by the process of elimination. This trick works well in the case of questions that have “All of these” as an option.

5. Make smart choices

The JEE questions are MCQ type and thus do not demand a complete procedure of how you reached the answer, it just requires a straight answer. So, you can make intelligent guesses, but do not rely on these completely.
