In your return line of code, you are referring to context variable but I don't see you assigned any value to this context variable in your code.

Or if you want to send three variables i.e. "fees", "total_fees" and "fee_remaining"... you need to send them separately like

return render(request, 'website/students.html', {"fees": fees, "total_fees": total_fees, "fee_remaining": fee_remaining })

then use these variables on your students.html template.
