Q: How do I try a free CIE 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 CIE IGCSE 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 CIE 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 Biology questions aligned to the CIE IGCSE syllabus?

Every question is written against the published CIE IGCSE 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 CIE 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 person with Type 1 diabetes has consistently high blood glucose levels. Which explanation correctly accounts for this condition?

Accepted Answer

C) Their immune system has destroyed the beta cells of the pancreas, so no insulin is produced — Type 1 diabetes is an autoimmune condition in which the body's immune system destroys the insulin-secreting beta cells of the pancreatic islets. Without insulin, cells cannot take up glucose from the blood, leading to persistently high blood glucose. Type 2 diabetes involves insulin resistance (option D), not Type 1.

Answer

A) Their pancreas produces too much glucagon, preventing glucose uptake

Answer

C) Their immune system has destroyed the beta cells of the pancreas, so no insulin is produced

Answer

D) Their muscle cells have become resistant to the effects of insulin over time

Answer

B) Their liver cannot convert glucose to glycogen even when insulin is present
