Hey Jagrati! For preparing NSO (Class 7, KV-2 Gwalior) in 2025-26, the most important thing is to first understand the syllabus and exam pattern. Start with your NCERT Class 6 and 7 Science books because most of the questions are based on those concepts. Along with this, keep practicing reasoning questions like patterns, series, and puzzles because logical reasoning is also a part of the exam.
Try to solve previous year papers and mock tests regularly; they help you in time management and also show your weak areas. Make short notes of formulas, definitions, and important concepts so that you can revise quickly before the exam. If possible, dedicate 1–2 hours daily for NSO preparation, and on weekends spend some extra time on practice tests.
Most importantly, stay consistent, revise regularly, and keep a balance with your school studies. A calm mind with regular practice will definitely help you perform well in NSO.
