UC App plus/minus grades

So I got in to UCLA a few days ago but a classmate just told me that when he self-reported grades, he put the pluses and minuses on the application (our schools uses an A-F system with + and -). I did not do that nor did I see that option. My B+s became Bs and A-s became As.

Is this true? If so, am I done? absolutely freaking out please help.

The UC Application does not accept +/- but the CSU application does so may be the classmate was mistaken.

When the UC and CSU calculate your GPA, they both drop the +/-http://www.csumentor.com/planning/high_school/gpa_calculator.asp
