Family's financial condition is at rock bottom. Need guidance for SSC CHSL preparation.

Namaste!

I'm 19 years old and my family's financial condition is very poor right now. I can't afford expensive coaching, and there's a lot of pressure on me to become financially independent as soon as possible.

I've decided to prepare for SSC CHSL seriously, but I'm confused about where to start and how to study efficiently.

My questions:

What books and free resources should I follow?

How many hours should I study daily?

If you cleared CHSL from a similar background, what strategy worked for you?

Any guidance, study plan, or motivation from those who have gone through this journey would mean a lot.

Thank you!
