Cambridge Lower Secondary Checkpoint scores students on a 0–6 scale per subject strand — not one overall grade. A score below 4.0 in any strand signals a specific gap that carries directly into Stage 10 IGCSE content. Source: Cambridge Assessment International Education
coremark.study is a library of downloadable PDF booster packs for Cambridge Lower Secondary students in Stages 7, 8, and 9.
The site covers three subjects: Maths (Cambridge syllabus 0862), Science (0893), and Computing (0860). Each booster pack covers one topic within one subject at one stage. Inside every pack: 20 practice questions at Foundation, Standard, and Stretch difficulty; full worked solutions with step-by-step methods; a one-page cheat sheet with the key rules for that topic; and a parent and tutor guide. A booster pack is designed for focused topic practice, not full-paper simulation — it complements Cambridge past papers and official textbooks rather than replacing them.
CoreMark is used by Cambridge Lower Secondary families in India and internationally. Students use it for Cambridge Checkpoint preparation, targeted revision before school tests, and to practise specific topics identified as weak by their school or tutor. All packs are available for immediate PDF download and are designed to be printed at home on standard A4 paper.
A coremark booster pack is a downloadable PDF containing a one-page cheat sheet, 20 practice questions at Foundation, Standard, and Stretch difficulty, full worked solutions with step-by-step methods, and a parent and tutor guide.

One topic at a time, everything in one download
My son always used to say I studied but I dont know why I got this wrong. After CoreMark for Place Value he could actually explain his mistakes to me. That was a big change.
We tried tuition, we tried YouTube. What worked was CoreMark. The cheat sheet is the best part, my daughter reads it before bed and does the questions next morning. Simple and it works.
The parent guide is what sold me. I am not a science person at all but it told me exactly what to look for when checking my childs answers. Very practical.
My son was completely lost with Python. Bought the CP2 booster and the cheat sheet alone was worth it. He finished all 20 questions in one go. No confusion at all.
