Q: How do I try a free CXC Mathematics question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CXC CSEC Mathematics bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CXC Mathematics students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Mathematics questions aligned to the CXC CSEC syllabus?

Every question is written against the published CXC CSEC Mathematics syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CXC past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

The table below shows the weekly wages of workers at a rum distillery in Barbados:

| Wage ($) | 400–499 | 500–599 | 600–699 | 700–799 |
|----------|---------|---------|---------|----------|
| Frequency | 5 | 12 | 8 | 5 |

In which class interval does the median wage lie?

Accepted Answer

500–599 — Award 1 mark for correct identification. Total frequency = 30, so median is between 15th and 16th values. Cumulative frequency: 5 (first class), 17 (second class). Since the 15th and 16th values fall in the cumulative frequency of 17, the median class is 500–599. A is incorrect — only contains positions 1–5. C and D are incorrect — cumulative frequencies exceed the median position.
