Need advice on earning while in college

Hey everyone.

I'm 19, from Kolkata, currently in college, and I've been trying to figure out a way to earn a bit more on the side.

I already teach a few students, so I do have some income, but tbh it's getting pretty mentally exhausting. A lot of the time my payment depends on the guardians, and overall I'm just not enjoying it anymore. I'm not looking to get rich overnight or anything, I'd just like to earn somewhere around ₹5k–15k a month.

I've also looked into freelancing, but as someone who's just starting out it feels really difficult to land the first few gigs, and some platforms expect you to spend money just to apply for jobs, which isn't really an option for me right now.

So I just wanted to ask if anyone here has been in a similar situation. What do you guys do to earn while you're in college? How did you get started? It doesn't have to be online either—I'm open to pretty much anything that's realistic for a college student.

Thanks in advance! :D
