Exam tips
- • Use correct biological terms — everyday words rarely score full marks.
- • Practise drawing and labelling the cell, heart, nephron and digestive system.
- • For genetics, always draw a Punnett square before answering.
- • Learn processes as ordered steps; exams often ask for the sequence.
