# Physics

Students generally feels drastic change and a lot of pressure when they enter in class 11th . Not only the previous chapters has been expanded to many folds but also new units like Heat and Thermodynamics, Rotational motion etc has been introduced.

Course Features

Most of the students of class 11th faces much increase in the difficulty level as they move from  class 10th . Now the subject needs a good grasp on the concepts as the questions are now mostly indirect and numericals type and along with that students also have to practice a number of questions. Many students also have started preparation for competitive exam. And all this makes class 11 th much difficult and creates mental buden on students.

Kenowit makes it easy for student by providing them - Lucidly explained content, teaching at student's individual pace, and discussion of every relevant types of questions and numericals required for students. Teachers at kenowit also guide students how to manage their school and competitive preparation in a planned way.

This course provides  high quality engaging recorded videos by IITians and live interactive classes with personalised Guidance and Quality practice questions for class 11th .
