Hello Rubal!

Yes definitely!

If you have confidence and self belief then why not. You must not repeat all the old mistakes. It is better to analyse your previous mistakes and prepare a on-paper guideline or chart for yourself in which you mention realistic targets which you are aiming to achieve every week or every month. It's better to not repeat concepts regularly but it is better to solve lots of questions throughout the week and revise concepts in weekend. Rest if you are joining some coaching then make sure to complete all of your sheets on time.

All the best!
