It’s quite common amongst students to find Maths as a difficult subject and find it hard to master. Many students of CBSE class 11 are phobic about math formulas, because of their negativity towards the subject and cannot focus or concentrate on math problems. Students have the most trouble before exams or even small class tests; that’s when nervousness kicks in. Due to the negativity and resentment towards math, most students fail their exams.

The only way students can get rid of the subject is by learning to get a strong grip on the maths formula. If students can do their best to be positive about maths formula, then they can achieve the kind of marks they desire. All those students need to do is to understand the concepts, learn all the necessary math formulas, apply these formulas according to the problem and then find the solution to that particular question.
