ISC Commerce Students: Which YouTube Channels/Teachers Helped You the Most?

Hi everyone!

I’m starting Class 11 soon and want to make the most of online resources for studying. Could you share which YouTube channels or teachers you found most helpful for each subject (or studying in general)? Whose explanations did you find the best?

My subjects probably are: Commerce, accounts, economics, business studies.

Also, if there are any websites that helped you with resources, notes, or practice, please let me know!

One more thing— What are your regrets and what you would do if you go back in time to start studying from class 11.

My boards are ongoing right now.

I am seeking free contents that does not require any sort of payment.

Thanks in advance.
