Note Taking

Useful notes are those you can actually learn from later — not the most complete or decorative ones.

The Purpose of Notes

Notes serve two purposes: capturing information while it is being delivered, and providing something useful to revise from later. These two purposes sometimes conflict. Good note-taking during a lecture prioritises capture; good notes for revision prioritise clarity and brevity.

The most common mistake is treating note-taking as copying — reproducing the source material in a different notebook. This produces a second textbook, not a study tool. Notes are most useful when they represent what the student understood from the material, expressed in their own words.

Starting point

Before your next note-taking session, write at the top of the page: "What are the three most important ideas in this topic?" Answer that question as you work through the material.

Note Formats

Outline Notes

The most straightforward format: main ideas at the left margin, supporting details indented beneath them. Works well for content with a clear hierarchy.

TOPIC: Photosynthesis Main point: Converts light into chemical energy Where: Chloroplasts in plant cells Inputs: Light, water (H₂O), CO₂ Outputs: Glucose, oxygen Main point: Two stages Light-dependent: Requires direct light Light-independent: Uses products of first stage

Two-Column Notes

Main ideas in a narrow left column; supporting detail and explanation in a wider right column. Useful when concepts need context to be meaningful.

CONCEPT | DETAIL ---------------------|--------------------------------------- Osmosis | Movement of water across a membrane Direction | From low to high solute concentration Example | Plant roots absorbing water from soil Plasmolysis | Cell loses water; membrane pulls away

Cornell-Style Organisation

Divide the page into three areas: a narrow left column for questions written after the session, a wide right column for notes during the session, and a summary strip at the bottom. The left column creates a built-in recall tool.

QUESTIONS (later) | NOTES (during session) --------------------|--------------------------------------- What drives osmosis?| Solute concentration gradient What is plasmolysis?| Cell shrinkage when water moves out When does it stop? | When pressure equals concentration SUMMARY: Osmosis moves water toward higher solute concentrations. Plasmolysis occurs when cells lose water to a more concentrated solution.

Concept Maps

Central concept in the middle; related ideas branching outward; connections drawn between related ideas. More useful for showing relationships than for capturing sequential information.

[Water Cycle] / | \ Evaporation | Precipitation ↓ | ↓ Condensation ←── Transpiration | Surface runoff → Collection

Comparison Tables

Items as columns; comparison features as rows. Makes similarities and differences visible at a glance.

FEATURE | PLANT CELL | ANIMAL CELL ----------------|-----------------|---------------- Cell wall | Yes | No Chloroplasts | Yes (in leaves) | No Vacuole | Large, central | Small or absent Shape | Regular | Irregular

Question-and-Answer Notes

Write the key question on one line; write the answer beneath it. During revision, cover the answer and attempt to recall it.

Q: What is the role of mitochondria? A: Site of cellular respiration; produces ATP for energy. Q: How does the cell wall differ from the cell membrane? A: Cell wall is rigid and structural (cellulose in plants); membrane is flexible and controls what enters/exits.

Summary Sheets

A single page written from memory after completing a topic. All materials closed. Contains only the most important ideas. Checked against original for accuracy. Dated and filed for revision.

Try this

After your next study session, spend five minutes writing a summary sheet from memory before checking any notes. The comparison between what you wrote and what the notes say tells you what actually stuck.

Reviewing and Improving Notes

Notes taken in a lecture or during reading become more useful if reviewed shortly afterward — within the same day if possible. Context that was clear during the session fades quickly. Gaps that would be easy to fill immediately become hard to fill a week later.

During review: add anything remembered but not written; mark any unclear points; write a brief summary of the session's main idea. This takes ten to fifteen minutes and significantly improves what the notes provide during later revision.

Common mistakes

Copying every word rather than selecting what matters
Spending more time formatting notes than understanding them
Never reviewing notes after writing them
Treating completed notes as equivalent to understanding the content

Reflection

Looking at your recent notes — are they brief enough to revise from quickly, or so complete that they reproduce the original material?
