Every year, students lose valuable marks in PSLE Science due to preventable errors. Understanding these common mistakes helps your child avoid them and score higher.
Top 10 Common Mistakes In PSLE Science
- Not Reading The Question Carefully
The Mistake: Answering what you think is asked, not what is actually asked.
The Fix: Read every question twice. Underline keywords like “not”, “most”, “least”, “explain”, “compare”.
2. Using Everyday Language Instead Of Scientific Terms
The Mistake: Saying “the plant grows towards light” instead of “positive phototropism”.
The Fix: Memorise and use scientific vocabulary. Markers look for specific keywords.
3. Incomplete Answers
The Mistake: Giving half an answer when two things are asked.
The Fix: Check if the question asks for multiple things. “State and explain” needs both.
4. Confusing Similar Concepts
The Mistake: Mixing up evaporation and boiling, or photosynthesis and respiration.
The Fix: Create comparison tables for similar concepts. Know the differences clearly.
5. Not Using Diagrams When Helpful
The Mistake: Trying to explain everything in words when a diagram would be clearer.
The Fix: Draw when describing processes, circuits, or life cycles. Label properly.
6. Wrong Units Or No Units
The Mistake: Forgetting units or using wrong ones (cm instead of m).
The Fix: Always write units. Check if they match the question.
7. Not Answering In Complete Sentences
The Mistake: Writing phrases or single words for open-ended questions.
The Fix: Always write full sentences unless specified otherwise.
8. Ignoring The Word Limit
The Mistake: Writing too much or too little.
The Fix: Check if there’s a word limit. Stay within it.
9. Time Management Issues
The Mistake: Spending too long on difficult questions and rushing others.
The Fix: If stuck, move on and return later. Allocate time per question.
10. Careless Calculation Errors
The Mistake: Simple arithmetic mistakes in data-based questions.
The Fix: Double-check all calculations. Use the calculator wisely.
Section-Specific Mistakes
Diversity:
- Not using classification keys correctly

How To Prepare
Review Past Mistakes: Go through old worksheets and tests. Identify patterns.
Practise With Purpose: Focus on weak areas rather than random practice.
Learn The Keywords: Every topic has essential vocabulary. Know them cold.
Time Your Practice: Simulate exam conditions during revision.
