HI,

Watching one shot videos will let you complete your syllabus soon, but the main aim of yours should be understanding concepts rather than hurrying up to complete the syllabus. Even if you complete the syllabus and try solving some questions you wouldn't be able to solve them and have doubts because you were busy completing the syllabus rather than focusing on the concepts.

So, I suggest you you to focus more on the concept rather than completing the syllabus. I am here to give you advices and the answers to your question but the choice is all yours. All the best and keep working hard.

Hope this helps.

Good luck.
