Need guidance

Hii, 18f, just joined a tier 69 clg, i don't wanna hear that i should have joined a better clg cause all the priv ones are so fucking costly and i fucking can't afford it. This clg will cost me around 12 lakhs, my father will cover 6 but the rest is entirely on me. And i wanna pay it off anyhow, so any job after clg will be very much helpful, even govt ones, so i need a proper guidance to pay off the 6 lakhs that will fall on me. Any jobs or exams that i should prepare for, any help regarding surviving clg, how to make sure that i maintain a good cgpa and prep for govn exams. What youtube channels should i follow, anything will help, thank you very much
