IGCSE Sciences - Co-Ordinated (0654) — real past-paper questions, marked by AI

Co-ordinated Sciences is the double-award route through biology, chemistry and physics, reporting two IGCSE grades for content that spans Papers 1 and 2 multiple choice, Papers 3 and 4 theory, and Papers 5 and 6 for practical work. Organic chemistry, forces and coordination and response all sit among the most-tagged topics, so a single revision session can cross all three sciences without ever feeling like three separate subjects.

This hub carries 3,524 real 0654 questions from 72 papers set in the May–June and October–November sessions of 2023 and 2024. Practical questions on electricity and enzymes both rank among the top topics, alongside reading instruments in the alternative-to-practical papers — a strong sign of where the scheme's marking points concentrate. Write your answer and the AI examiner marks it instantly against the real Cambridge scheme, showing exactly which idea earned the mark in biology, chemistry or physics content alike.

Sweep one topic at a time across the two years on the hub, then sit full timed papers. It is free, with no signup required.
