Safalta Expert Published by: Trisha Bharati Updated Fri, 12 Aug 2022 10:26 AM IST

The CBSE Syllabus is very important in assisting students in creating an efficient study schedule. For the 2022–2023 school year, the Central Board of Secondary Education (CBSE) has issued the class 12 revised syllabus. Studying the entire Physics can be daunting for students due to its complex numerical questions, theories and concepts. Therefore, to make it simpler and easier for you Safalta has taken an initiative and launched Safalta School Online where learning never stops. It offers a class 9 to class 12 online courses.
