Central Board Of Secondary Education [CBSE] — School is forcing students to give exams in school's sheets only and sheets can only be provided if we submit the fees till june..

I'm a student of class 11th. My father is poor drug distributor and due to corona virus our financial health is not so good. Kanaha Makhan Public School of Mathura is forcing parents in various ways to make sure that they submit their ward's fees recently they shared a message to our whatsapp group where they mentioned that students MUST appear in Unit test and test can ONLY be given on school sheets only . Now the problem is that they will not provide those sheets if we will not submit our fees till june which is around ₹3600 for two months
.Before this my father always deposit the fees on time, they had also INCREASED the fees by ₹200. They also mentioned that hard copies of exam sheet will be given to CBSE. There are many other students like me and many other families like us. Please take a step toward and help us .
