STEP 2024: Grade Boundaries, Papers and Practice
- Papers sat
- STEP 2 (9470) and STEP 3 (9475), each a 3-hour written exam marked out of 120
- STEP 2 official boundaries
- S 93 / grade 1 69 / grade 2 51 / grade 3 26
- STEP 3 official boundaries
- S 93 / grade 1 70 / grade 2 57 / grade 3 34
- How marks count
- 20 marks per question; only your best 6 answers count towards the total
- Difficulty (FrontierVUE catalogue)
- 9 of the 12 STEP 2 questions and 10 of the 12 STEP 3 questions are rated hard
The papers, boundaries and marking rules come from the official Explanation of Results for STEP 2024 and OCR's published guidance, OCR having delivered STEP from 2024; the difficulty line reflects FrontierVUE's own catalogue ratings, not an official assessment. Boundaries are reset by the exam board every year, so movement between years is normal.
