Master the A-Level: The Definitive Guide to Biology 9700 Practical Notes

Cambridge International AS & A Level Biology (9700) is renowned for its rigorous theoretical depth, but the Paper 3 (Advanced Practical Skills) and Paper 5 (Planning, Analysis and Evaluation) often separate the top achievers from the rest.

Unlike theory papers, the practical exams don't test rote memorization; they test technique, precision, and error analysis. You cannot "cram" for biology practicals, but you can master a set of core competencies. biology 9700 practical notes

Part 5: Statistical Tests (For Paper 5 – A2)

You will not calculate these by hand in Paper 5, but you must know which test to use and why. Part 5: Statistical Tests (For Paper 5 –

Part 9: Revision Strategy for Practical Papers

Do not simply read notes. You must do active recall.

B. Analysis of Data (Graphs and Statistics)

• What the notes cover: Types of graphs, error bars, standard deviation, and $t$-test.
• Review: Very strong generally.
  • Strength: The checklist for graph drawing (labeled axes, units, best fit line vs. line of origin) is usually perfect.
  • Statistics: The explanation of Standard Deviation (SD) error bars is crucial. Good notes explain that if SD error bars overlap, the difference is likely not significant. This is a frequent exam question.

4. Drawing a Graph (The 4 Marks that save you)

You will have to plot a line graph or bar chart.

• Scale: Use over 50% of the grid.
• Label: Axes with units (e.g., Time / minutes).
• Plot: Crosses (X) not blobs. Circles mean one point, crosses mean exact data.
• Line: Curves of best fit (smooth) or straight line of best fit (if the data is linear). Never join the dots.
