Help buy a computer for schoolwork

Hello!
I go to school and I have to use a computer at school, but I don't have one and that is a big obstacle to my learning.
Unfortunately, I live in a poor family and the family's financial situation is quite poor and unfortunately my family can't buy me a computer.
At school, it is mandatory for me to use a computer because without it, one cannot study this specialty.
I really hope I can buy a good computer for my schoolwork with your help.

NB:At school, I was told that if I didn't get a computer by the end of this year, I would be kicked out of school

Thanks in advance
Maario
