Yes ofcourse.
You know what i am doing the same. I hadn’t touched organic chemistry in class 11. And now I had prepared a study schedule in which I fixed my everyday study goals and was covering all those topics of class 11 which was left behind and also preparing for class 12. As I am studying through YouTube , there is a large varieties of videos available for you. You can watch their video lecture and after that you read read your books. That’s will definitely going to help you.
Hope it will help. Feel free to ask any further question.
Thank you!
