Common Mistakes
Mistake 1: Confusing similar concepts
Students often mix up related terms. Make sure you understand the specific meaning of each key word in efficiency.
Mistake 2: Forgetting to use evidence
Always support your answers with evidence and examples. Do not just state facts without explaining how you know.
Mistake 3: Not reading questions carefully
Exam questions often have specific command words like 'describe', 'explain', or 'compare'. Make sure you answer what is actually being asked.
Mistake 4: Rushing through practical work
Take your time with investigations. Accurate measurements and careful observations lead to better conclusions.
