CXC CSEC Human and Social Biology: Disease and Immunity FAQ
Is Kramizo free for CXC CSEC students preparing for Human and Social 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 Disease and Immunity practice with other Human and Social Biology topics or even switch to a totally different CXC 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 Disease and Immunity questions aligned to the official CXC CSEC Human and Social Biology syllabus?
Every question is written against the published CXC CSEC Human and Social 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 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.
How is Disease and Immunity typically tested on CXC CSEC Human and Social Biology papers?
Disease and Immunity appears across multiple question types on real CXC CSEC Human and Social 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.
