Syllabus and practice guide
A clear map of what the course covers, how it is assessed, and where real archive practice fits.
The short version
This double-award course combines Biology, Chemistry, and Physics while preserving each science's practical and reasoning skills. A useful study map keeps the three disciplines distinct, then deliberately mixes them when preparing for full papers.
Assessment at a glance
Co-ordinated Sciences uses a Core or Extended route plus one practical-skills paper. Multiple-choice and theory test knowledge and application; Paper 5 or 6 tests experimental planning, observation, data handling, and evaluation.
Core students take these two papers, then choose one practical-skills paper below.
Multiple choice
Theory
Extended students take these two papers, then choose one practical-skills paper below.
Multiple choice
Theory
Core and Extended students take either Paper 5 or Paper 6, not both.
Practical test
Alternative to practical
The archive spans more than one syllabus cycle. Timings and structures shown here describe the named current cycle, not every historical paper in the bank.
Historical topic frequency
Bar length compares topic-tag counts across the covered years. The longest bar is the most frequently tagged topic in this archive.
This is observed historical frequency: the strongest archive-backed estimate of relative topic prevalence, not an official syllabus weighting or a guarantee of what appears next. A question can carry more than one topic label, so counts can overlap.
Paper practice
Each page explains the archive slice, then opens the same bank explorer with the exact paper filter applied.
