NSEJS, conducted by IAPT, is the national-level exam that identifies and nurtures young talent in Science. The NSEJS syllabus covers Physics, Chemistry, and Biology based on Class 9 & Class 10 NCERT. As per the NSEJS 2026 exam syllabus, there is no Mathematics in the paper, as some pages claim. Even though the official syllabus states Class 9 & Class 10 level NCERT, NSEJS tests deeper conceptual understanding, application skills, and multi-step scientific reasoning through unfamiliar situations.
This guide covers the complete NSEJS syllabus along with important topics & a high-weightage chapters list. If you are new to NSEJS and curious about the question pattern, registration guide, or what the exam looks like, start with our Comprehensive NSEJS Exam Guide.
Understanding how much attention each subject demands and which chapters are the conceptual backbone of the examination is crucial for the NSEJS exam.

As per the current 2026 NSEJS syllabus, Mathematics is not included in the exam. The examination consists of Physics, Chemistry, and Biology.
The NSEJS exam syllabus is broadly based on science topics (Physics, Chemistry, & Biology) up to the CBSE Class 10 level, but the exam tests concepts through significantly more challenging applications and reasoning.
Yes, the NSEJS exam can be challenging for Class 8 students since they need to study topics/concepts beyond their current grade. However, starting as early as Class 8 gives them the advantage of building up their foundation gradually.
