Calculator policy
A graphic display calculator (GDC) from the IB-approved list is required for most Mathematics and Sciences papers and must be set to examination mode. Note that some papers do not permit a calculator (for example Mathematics Paper 1 and the multiple-choice Sciences Paper 1).

Mistakes
- In the high-pressure environment of the IB Biology exam room, the first five minutes are often where grades are made or lost. When handed Paper 1B or Paper 2, your immediate impulse might be to dive headfirst into writing. Resist this urge. Top-performing students use this time to systematically dissect data-based questions, particularly those featuring complex, multi-variable graphs. In recent past papers, many candidates fell into traps involving double-y-axis graphs, misidentifying which data point corresponded to which axis (such as confusing aerosol optical density with chlorophyll concentration). Spend the first few minutes circling the axes, writing down the exact units, and identifying the scales. This small habit prevents devastating misreadings and secures the foundational marks that set the stage for your success.
