Start with lots of energy and confidence.

Always feel motivated, and think that you will do awesome.

Do not leave the work for tomorrow, instead start from the day one.

In all the subjects the first chapter is easy and basic, so start with that chapter and try to understand the concepts rather than mugging it.

You can take the help of one shot videos as well as notes available on learnohun.com along with that, after finishing the chapter try to solve DPPs and online test.

All the very best for your wonderful start.
