Let's say you want to calculate the grade by simply turning it into a raw percentage (and not factoring in anything like that some questions might be worth more or some mistakes might be worth less than just knocking off all points for the problem).
We'll make x% be the percentage that you got right.
To calculate x% do:
(30-11)/30=19/30=63.333...%
You can round to 63%.
