Will my semester grades hurt my GPA?

I’m a junior, I need to have all A’s this year to bring up my grade to a 3.0 GPA. Right now the 1st semester (which ends tomorrow all grades are put in) I do not have all A’s only A’s B’s. Will that hurt my GPA? Or will only my end of the school year grades be added to my GPA?

Different schools do things differently, you would need to ask your guidance counselor whether your school uses semester or year-end grades to calculate GPA.
