The exam is held on two scheduled dates in the academic year. Each school selects one of them. Both sets of papers are different, but the format is always the same. This system allows schools to plan easily while making sure all students get a fair chance.
The syllabus includes science concepts already introduced in the school curriculum. The paper checks basic knowledge, observation and how well students can apply what they’ve learned. The language is simple, and the paper is kept level-appropriate. Students don’t need to use any external material, revision of classroom chapters is usually enough.
About two to four weeks after the exam, the official answer key is made available online. Students can go through it to compare their answers. It’s a good way to understand what went right, where they went wrong, and how to approach similar questions in future papers.
