Common Questions
Where are the video solutions for the May & November 2022 IB Biology SL Past Papers?

They’re coming! These videos will be published in the coming weeks.

What is the difference between May TZ1 and May TZ2?

IB examination sessions are held in May and November each year. For the May examination session, there are two different Timezones (with different exam papers): Timezone 1 (TZ1) for Latin America & North America, and Timezone 2 (TZ2) for Africa, Europe & Middle East & Asia-Pacific. The November examination session is Timezone 0 (TZ0).

Where can I get PDF copies of IB Biology SL Past Papers?

It is likely that your school will have access to all of the IB Biology SL Past Exams. It is therefore recommended that students ask their Biology teacher or IB Coordinator for copies of the exam papers and mark schemes. Alternatively, Biology SL Past Papers can be purchased from the Follett IB online store.
