What topics are covered in IB DP Biology (BI)?

Every topic and sub-topic in the IB DP Biology (BI) syllabus is covered on Tutopiya. Open any topic to see revision notes, video lessons, worked examples, practice questions and an AI-marked quiz. If a topic isn't clicking, book a 1-on-1 class with a Biology specialist.

How should I revise Biology on Tutopiya?

Start with the topic notes or video to lock in the concept, then drill practice questions to build speed, then take an AI quiz to see which sub-topics you've actually nailed. When you feel ready, attempt a full past paper under timed conditions. The report after each quiz tells you what to revise next — no guesswork.

What kinds of Biology practice questions are there?

Thousands of Biology questions, grouped by topic and difficulty — MCQs, structured questions, and exam-style problems pulled from real BI papers. Every question has a worked solution so you see the method, not just the answer.

Where do the Biology past papers come from?

All past papers are official IB DP Biology (BI) exams from previous years, with the original marking schemes. Practising with real papers is the fastest way to get familiar with the question style, the timing, and how examiners award marks.

How do the AI-marked quizzes work for Biology?

Take a quiz on any Biology sub-topic and the AI marks every answer instantly — including structured questions, not just MCQs. You get a report showing what you mastered, where you lost marks, and which specific sub-topics to revise next. It turns revision from "read everything again" into "fix what's actually broken".

Can I get a 1-on-1 Biology tutor?

Yes — browse tutors who specialise in IB DP Biology and pick one based on availability and student reviews. Book a trial class first. Your tutor can work through the exact topics you've flagged in your quiz reports, so no session is wasted revising what you already know.

How long does it take to prepare for Biology (BI)?

Most students start structured revision 8-12 weeks before exams. A good rule: split revision time into thirds — notes and videos, topic practice questions, and timed past papers. Tutopiya's progress tracker shows which topics are exam-ready and which still need work.

Is Biology content free on Tutopiya?

You can browse topic notes, watch sample videos and try practice questions without paying. A Tutopiya subscription unlocks unlimited AI quizzes, the full Biology video library and every past paper. 1-on-1 tutoring is booked separately — try your first class as a trial.
