Khan Academy is the first thing many parents of Cambridge Lower Secondary students try when their child needs extra maths help. It's free, well-made, and covers an enormous amount of maths content through short videos and adaptive practice. It seems like an obvious starting point.
The honest answer to "does it cover Cambridge Lower Secondary?" is: it covers most of the same maths, but it isn't built for Cambridge's curriculum, strand structure, or assessment style. That distinction matters more than it might seem.
What Khan Academy actually is
Khan Academy is a US-based non-profit that created a free online learning platform primarily aligned to US curricula — initially the Common Core State Standards, and more recently to the College Board's SAT curriculum. Its maths content is organised by US grade level (Grade 6, 7, 8 Math, then Algebra 1, Geometry, Algebra 2) and by SAT preparation.
Khan Academy also has an international reach and has partnered with curricula such as CBSE (India) and the UK's Oak National Academy, though these partnerships are for specific national curricula, not Cambridge International. There is no Cambridge Lower Secondary Mathematics (0862) course on Khan Academy.
Where Khan Academy overlaps with Cambridge 0862
The core mathematical concepts in Khan Academy's Grade 6–8 content overlap substantially with Cambridge Lower Secondary Stage 7–9. Most of the fundamental topics appear in both:
- Number: Fractions, decimals, percentages, ratio and proportion, exponents and powers — all appear in both curricula.
- Algebra: Writing and solving equations, graphing linear relationships, sequences — substantial overlap at Stage 7–8 level.
- Geometry: Area and perimeter, volume, angles, transformations — covered in Khan Academy's Geometry content.
- Statistics: Mean, median, mode, basic probability — covered in Khan Academy's Statistics and Probability sections.
For concept explanation and initial skill-building, Khan Academy videos are genuinely excellent — the worked examples are clear, the adaptive practice adapts to where your child is, and the mastery tracking is useful. Many Cambridge parents use it for exactly this purpose.
Where Khan Academy diverges from Cambridge 0862
| Area | Khan Academy | Cambridge 0862 |
|---|---|---|
| Strand structure | Grade-level courses (Grade 6/7/8 Math) | Four strands: Number, Algebra, Geometry & Measure, Statistics & Probability — reported separately |
| Assessment vocabulary | US math terminology throughout | Cambridge-specific command words: "show that", "work out", "write down" — each has a specific meaning in the mark scheme |
| Question format | Multiple choice and fill-in; adaptive | Method-showing, structured written answers; marks for working steps, not just final answer |
| Coverage gaps | Covers US curriculum topics not in Cambridge; misses some Cambridge-specific topics | Stage 9 topics like standard form and specific Cambridge geometry constructions may not be well covered |
| Worked solution format | Video walkthroughs; answers shown step-by-step | No Cambridge mark-scheme context — doesn't show where method marks are earned vs where the final answer earns marks |
The mark-scheme gap
Cambridge Checkpoint Maths awards marks for working steps, not just final answers. A student who gets the right answer by a different method to the one the mark scheme expects may lose marks. Khan Academy's practice format — which checks the final answer — doesn't train students to show working in the way Cambridge rewards. This is the largest practical gap between using Khan Academy and using Cambridge-specific revision materials.
How to use Khan Academy effectively for Cambridge revision
Khan Academy and Cambridge-specific resources are not competitors — they're different tools for different jobs:
The practical workflow is:
- Watch the Khan Academy video for the topic your child is stuck on (e.g., "Solving two-step equations" for Algebra revision).
- Do the Khan Academy practice until the concept is solid.
- Switch to Cambridge-aligned questions that require showing working, using Cambridge vocabulary, and earning marks at method steps — not just for the final answer.
Step 3 is what a CoreMark Maths booster provides: 20 Cambridge-style questions per topic, full worked solutions showing which steps earn marks and which are common errors, and a parent guide explaining the Cambridge command words and what "show that" or "write down" means in context.

Frequently asked questions
Khan Academy does not have a course mapped specifically to Cambridge Lower Secondary Mathematics (0862) or the Checkpoint assessment. Its maths content is primarily organised around US grade levels (Grade 6, 7, 8 Maths) and SAT preparation. Many of the same maths concepts appear across both curricula, but the strand structure, sequencing, topic coverage and assessment vocabulary are different from Cambridge 0862.
Khan Academy is useful for concept explanation — video walkthroughs of fractions, algebra, geometry and statistics are genuinely excellent for building understanding. Where it falls short for Cambridge Checkpoint revision is in the practice question format (not Cambridge-style), the strand terminology (Cambridge uses specific vocabulary that differs from US math), and the coverage (some Cambridge 0862 topics are missing, some Khan Academy content is irrelevant to Checkpoint). It works best as a 'concept explainer', used alongside Cambridge-specific practice materials.
There is no direct equivalent of Khan Academy built specifically for Cambridge Lower Secondary. The closest official resource is the Cambridge School Support Hub (accessible to teachers). For parents, Cambridge-aligned independent resources like CoreMark provide topic-specific practice questions, worked solutions and parent guides written for the 0862, 0893 and 0860 curricula.
