IOQJS Syllabus

One of the most popular exams in schools is the Indian Olympiad Qualifier for Junior Science (IOQJS) or NSEJS( National Standard Examination in Junior Science). It also helps you develop problem-solving skills early in your academics, which will improve your JEE and NEET scores. The Indian Olympiad Qualifier in Junior Science (IOQJS) exam aims to inspire students to evaluate their science skills by participating in a worldwide competition.

To better comprehend these ideas, students must be familiar with the essential topics of Physics, Chemistry, Biology, and Mathematics presented in the CBSE syllabus in lower grades. Since IOQJS is a secondary school test, students should begin their preparation by studying the NCERT texts for science and maths. In this article, we will discuss the IOQJS Syllabus in detail.
