Grade boundaries and grade calculator
Papers 1 and 2 are marked out of 100 and Paper 3 out of 70. OCR simply adds the three raw marks, so the overall boundaries are out of 270 (Papers 1 and 2 are 37% of the A level each and Paper 3 is 26%). Boundaries move every year with the difficulty of the papers, so use the last few series as a range, not a target.
