Simple 7-day study plan
This is a short plan you can repeat before tests. Adjust the pace to fit your schedule.
Day 1 – Cell & Microscopy
Focus on cell structure, organelles, and basic tools. Draw one neat, labeled diagram.
Day 2 – Cell Cycle
Learn stages of mitosis and meiosis. Make a small table that compares them.
Day 3 – Biomolecules
Write simple definitions and 2–3 examples for carbs, proteins, lipids, and nucleic acids.
Day 4 – Enzymes
Understand how temperature and pH affect enzyme activity. Practice one graph question.
Day 5 – Diversity of Life
Review basic groups and key traits. Create a one-page chart to memorize differences.
Day 6 – Plant Basics
Read photosynthesis and transport. Practice labeling leaf and root diagrams.
Day 7 – Human Basics + Ecology
Do a quick pass over systems (digestive, respiratory, circulatory, excretory) and then ecology terms. End with MCQs.
How to make notes that work
- One page per chapter: write only key ideas, formulas, and diagrams.
- Mark the “must know” lines: definitions, laws, and steps in processes.
- Teach a friend: if you can explain it simply, you understand it well.
- Use past papers: check what examiners ask most often and practice those.
