Physics Class XI
At Interactive Physics students gather complete knowledge of physics because it believes in result :
Students are generally afraid of numericals .Students are not able to understand the concepts in proper shape and the real problem begins right from here. They feel book language quiet tough but CBSE is based on NCERT so they have to go through the book but, generally, not be able to understand it properly and so inflating their problems many fold. At the other hand books which are available in market covers too much extra material and students hardly able to snatch sufficient time from their extremely tight schedule to go through the complete chapter and understand it properly.
According to us physics is a very interesting subject. Students who want complete knowledge of physics and selection in premiere institutes should take admission in Interactive Physics.
CLASS XI – A very important feature of the book is presentation. Students generally used to ask a question “Sir how we should present our answer in exam to earn 100% marks.
