fc 

fc means "full credit" and it is the opposite of hc meaning "half credit". my english teacher uses this certain type of grading system to grade essays and it can often be confusing to some people if they wanted to know what percentage or level (between 1-4) they got on their english essay. so an fc is anywhere between 70-100/3-4/a-b and an hc is anywhere between 50-60/1-2/c-d.

1. that was a wonderful essay, fc!
2. that was an awful essay, hc!

Fc means favorite cousin. They are someone who's always there for you. You can talk to them about everything. They're almost like your best friend.

My fc is always there for me when no one else is.
