Hello,

I hope you are doing fine, It's very good that you are going to get your preparation done through video lectures. Because it is more time efficient than attending coaching classes.

If you are searching for free video lectures on youtube then I would like to suggest you that stop this. Because none of the free video lectures are authentic and complete. If you are still searching for such free videos then you are wasting your time. You will only get advertisements there. Even if you find a good one.. You will get it as incomplete upload.

If you still wan to study from youtube only then i would suggest to go with -

1.Physics Galaxy

2.EduPoint

3.Ignited Minds

4.Math on go

5.Anytime padahi Acadedmy

6.Vedantu

Physics wallah

For Maths:-

1. Mohit tayagi

2. Math on go

3. COACHengg

4. Vedantu

For chemistry

1. Anytime padahi Academy

2. Gabbar Singh tutorial

3. physics wallah

4. Vedantu

I hope you find this information helpful. I wish you all the best for your future.

Good Luck

Hello.

You can easily get access to youtube videos for jee mains without any charge. You just need to google tutorials for jee mains and on your screen all the options will be shown. You can choose one of your choice. But it ks better to go with a channel that has more views and better reviews which you can check in the comment section. Also,you should go for channels that you are aware of and know are good. YouTube videos are more helpful as they are like being taught by a tutor and helps you understand complex topics easily.
