Q: Is Kramizo really free for CXC Human and Social Biology 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 Human and Social Biology questions aligned to the CXC CSEC syllabus?

Every question is written against the published CXC CSEC Human and Social Biology 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

A sports medicine doctor in Trinidad examined an X-ray of a teenage cricketer's arm following a collision during a match. The doctor noted that the bone had bent slightly but had not broken all the way through. Which type of fracture is this MOST likely to be?

Accepted Answer

Greenstick fracture — Award 1 mark for greenstick fracture. A greenstick fracture occurs when a bone bends and cracks on one side but does not break completely, and is most common in children and teenagers whose bones are still flexible. A is incorrect — a compound (open) fracture is one where the broken bone pierces through the skin. B is incorrect — a comminuted fracture involves the bone being shattered into multiple fragments. D confuses a stress fracture, which results from repeated minor trauma over time, with an acute bending injury.
