CBSE CLASS 11: AN OVERVIEW

CBSE Class 11 is a crucial year for students because it sets the foundation for all the important topics that will be covered not only in class 12 but in further studies too. It is important to study sincerely in Class 11 not only for the CBSE Board exams but also for the competitive exams that will ensure entry into a good college. Students should utilize the Class 11 academic year to build their basics, doing so will help them to face the board exam confidently next year.

SpeEdLabs offers courses for Maths which is not only designed to ace the CBSE board exams but also make the students ready for Engineering and Medical Entrance tests. The CBSE curriculum framework is designed to ensure that students are not under great pressure and that books are made interactive and interesting. Also, many fun activities are included in the chapters making the whole process of passing on information to students effective and healthy. ## Scheme For Theory Examination [80 Marks]:
