What parents are saying

Real feedback. From real families.

★★★★★

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.

Parent · Mumbai · Stage 8

★★★★★

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.

Rajesh K.

Parent · Bengaluru · Stage 9 Science

★★★★★

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.

Common questions

Things parents usually ask.

No. CoreMark is not affiliated with or endorsed by Cambridge Assessment International Education. These are original practice papers written in the style of Cambridge Lower Secondary Checkpoint. They are not past papers and not official Cambridge material. They are written specifically for topic-focused practice and concept building.

Stage 7 is roughly Year 7 or Class 7, Stage 8 is Year 8 or Class 8, and Stage 9 is Year 9 or Class 9. If your child's school follows the Cambridge Lower Secondary programme, the stage will match their year group. If you are not sure, start with Stage 8 and see how your child gets on with one pack before buying more.

As soon as payment is confirmed you will receive an email with a download link. You can download the PDF immediately and print it at home on any A4 printer. The link stays active so you can re-download if needed.

Yes. Once you download the PDF you can print it as many times as you like for your own household. If you have more than one child at the same stage they can both use the same pack. Please do not share the PDF with other families as that is not permitted under our terms.

Absolutely yes. The topics covered in CoreMark boosters are standard secondary school topics across all major curricula including CBSE, ICSE and state boards. The questions are built around concept clarity and exam technique rather than any one board's exact format. Many Indian families use CoreMark even without a Cambridge school.

We offer a 7-day money back guarantee. If you are not satisfied with any purchase for any reason, email us at info@coremark.study within 7 days of purchase and we will refund you in full. No questions asked.

Yes, many tutors use CoreMark boosters in their sessions. Each pack is designed to be a complete 25 to 30 minute practice session. The worked solutions and error flags save tutors the time of preparing materials from scratch. For classroom use with multiple students please contact us for a school licence.

Please email us at info@coremark.study and tell us the pack code, question number and what you think is wrong. We review every report and update packs when needed. Every pack improves with every student who uses it and we genuinely appreciate the feedback.
