Not a black box — numbers you can check yourself
55 raw points, one formula, a ±0.3 range, and the real CEFR cutoffs — exactly how your Speaking band is calculated.
Building the raw score: 55 points across 11 items
7 Listen and Repeat items, each 0-5, for up to 35 points — plus 4 Take an Interview items, each 0-5, for up to 20 points. 35 + 20 = 55 raw points total.
Raw score → band, worked example
One formula: band = 1.0 + (raw ÷ 55) × 5.0, rounded to the nearest half point.
A real example
Raw score: 44 / 55
Band: 5.0
Why your summary shows a range, not one decimal
No single practice test pins your ability down to an exact decimal. The app shows a ±0.3 range around your band — a 5.0 becomes 4.7–5.3 — a more honest picture than false precision.
Band → CEFR, and the calibration behind it
6.0+ = C2, 5.0+ = C1, 4.0+ = B2, 3.0+ = B1, 2.0+ = A2, below that = A1. And Take an Interview's own grading is deliberately calibrated to reward a genuinely strong answer with a 5 rather than default low — 0-2 is reserved for answers that are barely responsive or off-topic, not just imperfect.
