College forcing students to pay the fees

I am an Engineering students whose fees is 1,36,000 for the academic year 2020-21 and the college is forcing to pay 50% of the fees by August 15, 2020. But for a student like me who belong to middle class family paying 50% of the fees during the covid situation is still difficult as we face difficulties for our basic need over these past months. I talked to the college stating my difficulties but still they want me to pay the 50% of the fees before the deadline. So what are the correct ways that I can act legally regarding the issue?
