The evaluation is one of the highest-scoring sections of the Chemistry IA —
yet most students write it in a rushed paragraph.
Here's how to write a clear, structured, examiner-friendly evaluation.
Examiners don't want:
❌ "Human error occurred."
❌ "We could have used more accurate tools."
They want:
✔️ Specific
✔️ Scientific
✔️ Measurable weaknesses
Examples:
Each weakness must have a realistic improvement.
❌ "Use better equipment."
✔️ "Replace manual titration with an automatic titrator to reduce end-point variability."
For each weakness → explain:
This is where marks jump.
One sentence:
"The reliability of the conclusion is limited due to the experimental weaknesses identified, particularly X and Y."
Clear. Mature. Examiner-friendly.
