The 0606 grade checker

Enter the two paper marks from any past paper, mock or school test. You get the total out of 160, where it sits against the indicative Cambridge IGCSE Additional Mathematics thresholds, and the gap to your target in marks — free, no sign-up, and the result lives at a link you can share.

Check a mark

What the thresholds have typically looked like

0606 is marked out of 160, two papers of 80 each, equally weighted. The indicative pattern from published threshold tables, always to be verified against the official Cambridge grade threshold tables for your session:

Grade Indicative range Of 160 marks
A* ≈ 80–87% ≈ 130–140
A mid-60s to low-70s % ≈ 105–115
Below A Steps down in roughly even bands; varies by session — see the full band pattern →

Most recent published example — June 2024: A* 132–135, A 105–110 out of 160, varying by paper option.

Thresholds drift a handful of marks between sessions, which is why the grade boundaries guide recommends training at 90% rather than at the historical line, and why the A* plan is built on surrendering nothing.

Checker questions, answered

Is this the official 0606 grade calculator?
No. Cambridge sets 0606 thresholds after marking each session, so no tool can tell you the exact boundary in advance. This checker uses the indicative pattern from published threshold tables to place a mark in context, and always links you to the official Cambridge tables for your session.
Why does the checker give a range instead of an exact grade?
Because the real boundaries move a handful of marks between sessions — even within one session they vary by paper option (June 2024: A* was 132–135 of 160). A* has generally landed around 80–87% of the total, and A typically in the mid-60s to low-70s percent. Anything more precise than a range would be a guess, so we don't pretend otherwise.
What should the practice target be?
Train at 90%, around 145 of 160, if the goal is an A*. That margin absorbs both threshold movement and exam-day friction, so the moving boundary never decides the grade. For an A, train at 80% for the same reason.
The mark looks low. Should we panic?
Not from a percentage alone. 0606 is a single-tier subject that stretches from E to A*, so mid-grade thresholds sit lower than parents expect, and a 60-something percent can be a respectable grade in a hard session. The useful next step is a marked script review, which is what the free trial lesson includes.

An estimate is a start. A marked script is an answer.
