Understanding and Interest are key to get success in maths…  Basically don’t memorize the formula.. Try to understand the basics and try to frame a formula..   Workout lot of examples and make it correct.. learn all the shortcuts and create some shortcuts then discuss with your friend too..

hmmm, but for some people, they wont understand well and they dont have facilities, for them what is the solution?
To do good in maths is to PRACTICE each and every sum.And it is not always that we get similar sums so be prepared to do something new always.
If u cant solve any sum try twice if still u cant get the ans u mark the sum and do at last.
We often loss concentration and confidence , so just Chill and try A to Z as a Beginner
