Hello Amit,
All you score are very good but your score in English is low.
You just need to work on your Verbal Ability.
Refer to CAT study materials.
A tip I would give is- There are 3 comprehensions given. Do only the 2 smaller ones and leave the lengthy one. Read it carefully at least 2 times and answer the questions.
You can watch videos by Dinesh Miglani on YouTube. Check his playlist, he has some good explanations.
All the best!
