Study and Test Tips
- Understand the concept, not just the definition.
Science questions often test comprehension, not memorization. Try to grasp how and why things happen. - Visualize when solving.
For topics like physics or earth science, picture what’s happening. Diagrams and mental images can help. - Eliminate wrong answers.
If you’re unsure, rule out the clearly incorrect choices first to increase your chances of picking the right one. - Watch out for trick words.
Words like always, never, and only can change the meaning of a statement completely. - Apply logic and reasoning.
Even without memorizing formulas, you can often deduce the correct answer by understanding the situation.
Understanding science is essential for making sense of the world and for making informed decisions in everyday life. From health and nutrition to climate change and technology, science affects nearly everything we do. Strengthening your knowledge in science builds not only curiosity but also critical thinking and problem-solving skills.
