hello aspirant...

hope you are doing good.

for revision purpose, it is a very good idea. In JEE preparation, one shot videos are very efficient and effective. They're usually used in the final stages of preparation. However, they are only useful if you are well-prepared and want to revise an entire chapter in a short amount of time.

You can use one shots if you know some basic information about a chapter and want to cover at least 70% of the chapter. However, you can try pyqs after that. One shot gives you a good understanding of the chapters.

there are many channels in which you cannot understand the topic  and then you will have to check them in other video for detailed chapter lectures.

Hope this information helps you...

all the best.
