ptcb exam score to pass
(INDIANAPOLIS). I have question. about the new ptcb scoring, recently they change score, before 300 to 900 passing rate was 650. now 1000 to 1600 passing rate is 1400.0 out of 90 isn't right... by: Anonymous. That's not true either. There are 90 questions, but only 80 are scored, thus removing the idea that you have to get 80 out of 90 right-then that would be a perfect score.
