Practice that's built around the topic, not the exam

What CoreMark is

CoreMark is a publisher of printable PDF practice resources for students following the Cambridge Lower Secondary programme. Each booklet covers a single topic — not a mixed bag of questions across the whole syllabus — so students and tutors can isolate exactly where a gap exists and close it efficiently.

Booklets are sold individually (₹249 per topic) or in bundles by subject or stage. They are delivered instantly as downloadable PDFs, printable at home on any A4 printer.

What's inside every booster pack

Every CoreMark booster pack contains four components, written for the specific topic — not adapted from a generic template:

• 📋
  Cheat sheet — a concise reference of the key rules, formulas, and definitions for the topic. Designed to be read before practice, not after.
• ✏️
  20 practice questions — graded across three levels: Foundation, Standard, and Stretch. Questions are written in the style of Cambridge Lower Secondary Checkpoint assessments.
• ✅
  Full worked solutions — step-by-step reasoning for every question, not just final answers. Each solution flags the common mistake students make on that type of question.
• 👪
  Parent and tutor guide — a short guide explaining what the topic tests, how to spot if the student has understood it, and what to try if they're still stuck after working through the pack.

Why topic-by-topic

Most Cambridge practice material comes in the form of mixed-topic past-paper style tests. These are useful for exam simulation, but a poor diagnostic tool. A student who scores 14/20 on a mixed paper has learned almost nothing about where the 6 missing marks went.

Working one topic at a time — cheat sheet, then focused practice, then checking solutions against the reasoning — is a faster route to closing specific gaps. CoreMark is built around that approach.
