Performance Analytics
Access the definitive 19-year (2007-2025) dataset for Cambridge STEP 2 and STEP 3. Our dashboard visualises the volatility of grade boundaries, comparing the “Grade 1” admission threshold against the elite “Grade S” benchmark to help you define a safe target score.
Strategic Insights from the Data
Insight 1
The Admission Standard (Grade 1)
For most Cambridge colleges, a Grade 1 is the mandatory offer condition. The long-term average for this threshold sits at 69.8 (STEP 2) and 63.7 (STEP 3). Achieving consistency above these specific markers is the primary goal for every applicant.
Insight 2
The Elite Benchmark (Grade S)
The data reveals a massive score jump required to achieve the top S grade—averaging 93.0 in STEP 2. This ~23-point gap quantifies the significant difference in mathematical maturity between a qualified candidate and an exceptional one.
Insight 3
Boundary Volatility
STEP grade boundaries are notoriously volatile. As shown in the line charts, the Grade 1 cut-off can swing by over 20 marks depending on the year’s paper difficulty. A static raw score strategy is unreliable; preparation must focus on the ability to solve complete questions.
