Laptop for schooling

Hello! Im currently studying aa senior high school student and we all know this pandemic caused too much trouble already. Im asking for your help, small or big amount. My old laptop is broken which I used in class. I dont have money to buy another one. We’re not financially stabel that’s why im asking for any amount. Im planning to buy a second hand laptop because I know it cost less than the brand new one. Hope you could help me. Thank you :
