how does the rating system work?

I keep getting WA in my answers for recent competitions, and I began to wonder how it affects my rating, which lead me to the title’s question.

@zackscary : Rating system does not depend on number of attempts in a LONG contest . For a LONG contest your rank at the end of contest based on your score ( which does not depend on number of attempts , before solving or without solving ) .

However for SHORT contests , ties are broken according to total time taken and there is a penalty of 20 minutes for every wrong submission . In the end your rating again is based on your rank in the contest , but as you see rank depends on score and total time taken both .
