Turn your exact syllabus into a study plan
Start with your curriculum, subject and level, then use the syllabus to choose a topic. Course guides explain what to study; Notes explain the ideas; Question Bank helps you apply them to exam questions. Check the resources available for your selected course.
Match your syllabus and assessment
Check the course version and assessment structure before planning revision. For IB Biology, choose SL or HL so your topic list and paper information match your level.
Review one topic, then attempt questions
Choose a syllabus topic, read the available Notes and explain the idea in your own words. Then use the matching Question Bank to practise applying it and check the supplied answer guidance.
Use your answers to plan the next step
Identify the missing concept, calculation or explanation in an answer. Return to that syllabus point before trying another question. Use additional study tools where available.
Find the course that matches your syllabus
Use the course information from your school to confirm your curriculum, exam board, full subject name and level. These choices keep your syllabus, practice and progress connected to the course you actually study.
Confirm your curriculum
Start with IB, A-Level, IGCSE or AP. The same subject can follow a different syllabus in each curriculum.
Match your exam board
For A-Level and IGCSE, check whether your school follows Cambridge International (CAIE) or Pearson Edexcel. Choose the matching exam board before selecting your subject, so you use the right syllabus structure. Browse CAIE A-Level courses, Edexcel A-Level courses, CAIE IGCSE courses or Edexcel International GCSE courses.
Choose the full subject name
Match the course name on your school timetable or exam entry to the subject in the directory. Where there are different course routes, choose the exact one you study rather than relying on a broad subject label.
Check your level or course stage
If your course offers a level or stage, select the one you study: for example, IB SL or HL, A-Level AS or A2, or IGCSE Core or Extended where available. SL and HL are alternative course levels, not a sequence of courses to complete. Options vary by subject and exam board; use the choices shown for your course.
What you can do after choosing a course
Open the course syllabus to find your next topic. Use the available Notes to understand the ideas, Question Bank to practise exam questions, and Documents to find supporting study files. Resource availability varies by course; check the course page for what is ready to use.
Confirm your course with your school and the official information from IB, Cambridge International, Cambridge IGCSE or College Board.
Common questions
Choose the IB subject you study, then select Standard Level (SL) or Higher Level (HL) to match your school enrolment. Use that course branch for your syllabus and learning progress.
Confirm your exam board with your school before choosing a subject. Cambridge International (CAIE) and Pearson Edexcel have separate course entries. Select the available AS or A2 stage that matches your course.
Open your IGCSE exam board and subject, then choose Core or Extended if those routes are available. These options do not apply to every subject or exam board; check your school exam entry.
Open the AP directory and match the full AP course name to your school course. Select the specific entry shown in the directory so you follow its syllabus.
Where these tools are available, use Diagnostic to identify topics that need attention within your chosen course and syllabus range. Use Practice to work on those units, topics or knowledge points. When signed in, completed practice contributes to the mastery shown on your Course page.
Resource availability varies by course. After choosing your syllabus, check the Course page and the relevant Notes, Question Bank or Documents section to see what is ready to use.
