Little weird! But I still want to know, is a C- lower then a C? Just want to know, thanks~Karma!

Answer 1

C minus is 70-72%
C is 73-76% :)

You can look up "School grades" on google and it should give you the answers if this didn't help

Answer 2

C-lower then C it still stays a C 
ex: C-C=C or C+C=C
