ABOUT "THE SCIENCE CUBE"
Physics for class 11 and 12 is a significant step-up from class 10.
"The Science Cube" has come about from my experience of teaching over the years and how intricate topics like "integral calculus", vectors, Newton's laws of motion etc. are absorbed by young students.
I really hope that this channel can make the students appreciate the subject and help them ace their exams.
Who can use:
Class 11 and 12 students (CBSE, ICSE, NCERT)
IIT-JEE Preparation (JEE Main and JEE advanced)
K-12
Advanced Placement (AP Physics)
