Q: How do I try a free CXC Human and Social Biology 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 Human and Social Biology 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 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

Why does the left ventricle have a thicker muscular wall than the right ventricle?

Accepted Answer

C. It must generate greater pressure to pump blood through the systemic circulation — The left ventricle must pump blood through the entire systemic circulation, which spans the whole body and requires high pressure. The right ventricle only pumps blood the short distance to the lungs at lower pressure, so it needs less muscular force. The thickness of the ventricular wall reflects the workload required of each chamber.

Answer

D. It contains oxygenated blood which requires more muscular effort to process

Answer

A. It pumps blood a shorter distance to the lungs

Answer

B. It receives blood from more veins than the right ventricle

Answer

C. It must generate greater pressure to pump blood through the systemic circulation
