* Current in a circuit is somewhat analogous to the flow of water in a closed system of pipes,with gravity playing the role of the electrostatic field,and a pump(motor) as a role of battery. In this sense, height is analogous to voltage.

 To get marks 90% in maths , solve all the questions of ncert part 2, and please also carefully solve solved examples. It's not difficult if you finish one chapter in one day,some chapters may take 2 days but you can finish the whole book within 10 days if you work really hard.
After having finished ncert part 2, try to solve subjective questions from question bank. 
 Bass itna karlo emaandari ke sath,90% is garanteed to you 💪.

For highest confidence--->integrals, differential equations, matrix and determinants, applications of differentiation and integration, continuity and differentiability,..... Itna ko sabse achha se prepare krlena 👀.




"If you want to get 90% then 
You have to study more than this list"
