Join our expert tutor, Carly, as she provides you with IB Biology SL/HL. Over five days, she will help you deconstruct IB-style questions, identify essential concepts and utilize key terms to score big in your exams. Don't worry if you are studying Standard or Higher Level; she will treat both content levels separately on different days.

See our detailed curriculum breakdown to see what Carly is covering each day; you can choose to study the topics you need per Standard/Higher levels or Higher level only days or the whole course! Sign up today.

This revision course is designed to cover key ideas and common misconceptions of the entirety of the IB Biology curriculum. As an experienced IB Biology teacher and IB examiner, I have selected the key concepts which students often need more support for as the main components of each lesson. Students will be asked to give their feedback before the course begins about which topics they would prefer to focus on each 3-hour session, depending on which topics were covered in their 1st year of the IB Biology Diploma Program. The HL topics are built off the SL topics, with two HL-specific sessions planned in the middle of the five days and are designed to balance the workload between SL & HL students.
