How to earn money as 17 yrs old ?

Hi, I am a 17 yrs old boy (will become 18 in March), currently giving college entrance exam. I belong to a very middle class family, my father with his 2 brother run a shop and taking take of 13 members of the family (including them). I don't have a laptop (hopefully will get soon), I have a vivo Y20G. I want to lift off the burdern from my family and try to make my family a comfortable life in which my father along with his brothers don't need to run a shop, they just need to relax. They are working since the age of 14 as two generation in our family hasn't earn any money (my grand father and great grand father).

So pls help and tell me a way that i can do that in part time along with study
