Course description

It is very important for students to perform well in Class 8 because of various reasons. Firstly, the syllabus of Class 9 and Class 10 Science is very closely related to that of the CBSE syllabus of Class 8 Science. So, if you do not understand the concepts properly now, you will face difficulty later. Second, if you are planning to appear for competitive exams in the future, like NTSE and Olympiads, you have to be prepared to face higher-level questions that need a clear understanding of the basics and a very strong foundation. This means every single concept in the latest NCERT syllabus for Class 8 Science must be finished thoroughl
