Through this exam, students are selected for the International Junior Science Olympiad (IJSO). NSEJS is designed only for students studying in Class 10 or below and is conducted at many centres in India. This article will provide the best compelling tips and ideas on how to prepare for NSEJS 

NSEJS tests students’ conceptual understanding, logical reasoning, laboratory skills, and most importantly, problem-solving skills in novel situations, both theoretical and experimental. The main purpose of NSEJS is to select students for IJSO. Top scorers of NSEJS will get a chance to appear in Indian National Junior Science Olympiad (INJSO) conducted in January 2022.
