I'm very weak in solving numericals. How can i become good in it?

Hello ,

The only way to become strong in numerical is practice . But before that you must know few things those are :-

1. Proper Theory
2. Proper Formulae
3. How and where to apply which concept , logic and formulae .

The first two , you have to learn and for achieving the third one you should do practice as much as you can , look few solved examples and try to understand what is the concept and logic applied in that particular question or problem and then solve unsolved questions by your own and try to implement what you have learnt from the solved examples and theories you have read .

But the most important factor is how much you practice . So , follow above steps and I hope so it will help you .

Good Luck .
