CXC CAPE Biology: Genetic engineering and its applications FAQ

Is Kramizo free for CXC CAPE students preparing for Biology?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Genetic engineering and its applications practice with other Biology topics or even switch to a totally different CXC CAPE subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Genetic engineering and its applications questions aligned to the official CXC CAPE Biology syllabus?
Every question is written against the published CXC CAPE Biology specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CXC CAPE paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CXC CAPE.
How is Genetic engineering and its applications typically tested on CXC CAPE Biology papers?
Genetic engineering and its applications appears across multiple question types on real CXC CAPE Biology papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
