The exam happens on two different dates. Schools decide which one to follow. The paper sets are separate, but the structure is the same. That keeps things fair and avoids confusion.
All questions are based on science topics already taught in school. There is no extra syllabus. A regular round of revision from class notes is enough for most students. The questions test understanding and simple logic.
The answer key is released online after the exam. Students can check which answers were correct. It helps them go back and look at what they missed or misunderstood.
