Tawjihi life sciences is a large subject, but its questions follow clear patterns: explain-why, compare, diagrams and genetics problems.
The four units
- Cell processes: photosynthesis, the Calvin cycle, cellular respiration, the genetic code and protein synthesis.
- Genetics: Mendelian inheritance, incomplete and co-dominance, sex linkage, linkage maps, disorders, biotechnology.
- Human body systems: skeleton, heart and blood, immunity.
- Microorganisms: bacteria and viruses.
An explain-why answer needs a scientific reason, not a restatement of the question.
How to practise
- 1One lesson per session.
- 2Two genetics problems every other day.
- 3Read the “What to study next” card after each exam.
