NCERT Books for Class 8

Class 8 is the first important milestone in a student’s learning journey. Class 8, in many ways, define and orient a student’s performance in class 10th Board and other competitive exams at this level e.g. Olympiad, Scholarship exams, NTSE etc. There is a growing trend that students complete their primary phase of learning Life & Technical skills e.g. Coding, Robotics, Foreign Languages etc. and graduate to the intermediate / advance phase. Also, many students enroll for preparing for Engineering and Medical entrance level exams. So by this stage, students have to be well-versed with the the fundamental concepts, their application and be methodical towards their learning outcomes.
