Maintain neat, complete laboratory records with proper diagrams, observations, and conclusions. Include photographs where appropriate, ensure regular updates, and seek teacher feedback. Quality presentation significantly impacts marks.
Examination Strategies
Q16. What is the optimal question-solving sequence during exams?
Start with multiple-choice questions for confidence building, then proceed to short answers you’re most confident about, followed by remaining short answers, and finally long answer questions. Save most challenging questions for last.
Q17. How should students handle exam stress and anxiety?
Maintain regular exercise, adequate sleep, and healthy nutrition. Practice relaxation techniques, maintain realistic expectations, and focus on preparation rather than results. Seek support from teachers, family, or counselors when needed.
Q18. What should students do if they encounter unfamiliar questions?
