Our Detailed Analysis for RSO:
From analysing RSO past year papers from 2015-2025, we have observed the following:
- RSO questions are classified into 5 main modules – Astronomy, Earth Science, Life Science, Physical Science and Data Analysis. As RSO questions are more challenging, students will need to be familiar with lower secondary science topics.
- Mastering the 5 main modules (Astronomy, Earth Science, Life Science, Physical Science and Data Analysis) is essential for students to excel due to the highly competitive nature of RSO.
