IB Biology flashcards

Break terminology into roots, prefixes, and suffixes where possible, and always learn a term alongside its function rather than in isolation. Flashcards work particularly well here because you can test yourself on definitions in both directions. Regular, short review sessions spread over weeks are far more effective than trying to memorise long vocabulary lists the night before an exam.

Yes, very much so. Annotated diagrams of structures such as the heart, nephron, chloroplast, and mitotic stages help you encode spatial relationships that written notes alone cannot capture. Practising diagrams from memory also acts as a form of active recall. Neat, labelled diagrams are frequently rewarded in exam answers, so making them part of your regular revision routine is genuinely worthwhile.

Practise reading axes carefully, identifying trends and anomalies, and always referring to specific values from the data in your answer. Avoid vague statements and instead quote figures with units. Work through as many past data questions as you can find, then compare your responses against mark schemes to understand the level of precision expected. This skill improves significantly with deliberate, repeated practice.

Genetics, particularly dihybrid crosses and chi-squared analysis, and the detailed biochemistry of cellular respiration and photosynthesis are commonly found difficult. Human physiology topics such as the immune response and kidney function also require careful, precise learning. These areas reward students who revisit them multiple times using active recall rather than simply re-reading, so allocate extra revision sessions to them early.
