解决方案

You would get all the marks for that student, and you''d need to know the maximum possible marks. Dividing these gets you a percentage which is generally how a grade is calculated.

If your work is due in 2 days, it''s a bit late for you to be trying to understand the requirements. We''re happy to help, but we don''t help faster based on your demands, we''re not being paid, so please don''t ask us to reply ''as soon as possible'', we will, by definition, reply ''when we feel like it''.
