Dear student,

The best way would be to go for online platforms like youtube, byjus, etc. Where you can learn at your own speed. You can even ask you doubts at these platforms or you may ask them in your tuition classes. In tuition classes, a teacher is not able to focus on each and every student and every student has a different grasping power. So I would suggest you to read more theory books and understand those topics in a very interesting way on these platforms. You can get almost everything on the internet.
