Biology 9700 Practical Notes Review

Connect points with straight lines using a ruler if the intermediate values are unknown, or draw a smooth, balanced line of best fit if a clear underlying continuous trend exists. Never extrapolate the line beyond your first or last plotted data points. 6. Identifying Errors and Suggesting Improvements

Never use vague words like "amount" when you mean "volume" or "concentration". Never say an enzyme was "killed" when it was "denatured".

Not enough data points to establish a clear trend.

Use a sharp HB pencil. Never use a pen, colored pencils, or shading. Connect points with straight lines using a ruler

Only draw the outlines of tissue layers.

Only draw internal structures if they are visible (e.g., guard cells, chloroplasts, or nuclei). Never draw structures from memory if they cannot be resolved on the slide. 6. Identifying Errors and Suggesting Improvements

To conclude, effective preparation for the 9700 Biology practical papers is about combining knowledge with strategy. Use the syllabus as your ultimate checklist to cover every objective. Remember that the practical papers are not separate from your theory—skills like enzyme kinetics or genetic crosses, which are tested in Papers 3 and 5, also form the basis for your A2 theory assessments.
