38:13 ...whoever has sent the hateful comments, I don't feel pity for, you should be ashamed. Such a great teacher ! Such a personality is giving you the BEST lectures without charging you! unlike the boring ones you have in your school for which you pay, if you can't say something good, then it's better not to say anything. Because you people don't realise that in those 10 seconds of your life in which you write a hateful comment about someone you haven't even seen in real life can put that person into so much self doubt that the person might reconsider his work, his decision to provide free and quality education to people ! Doesn't matter what you feel, he receives hundreds of such messages on his videos, he too feels sad but he looks to the thousands who love him dearly and every lecture starts with a brilliant smile.
Keep it up sir.
You have no equavalent.
Respect.

Alak Sir, I wanted to express my appreciation for your teaching style. When I study from other teachers, even 30-minute videos feel overwhelming. But with your classes, even 1-2 hour sessions feel engaging and pass by quickly. Your ability to make complex concepts enjoyable and easy to understand is truly remarkable. Thank you for making learning such a pleasant experience!
