Hello Yashika,

Since one 2 months are left for CAT, usually devoting 7-8 hours daily will work if you are aiming for 100 percentile. It is because mainly the contents are aptitude, reasoning and verbal ability. I would suggest you to divide the time and give time to focus on your weakness. If you have more bandwidth, utilize them and give more Mock tests. Because CAT is fairly not a difficult exam But the difficulty lies in the time management. The best books would be:

Logical Reasoning Books:

• Nishit Sharma's Logical Reasoning and Data Interpretation
• A Modern Approach to Logical Reasoning by R.S. Agarwal

Verbal Ability Books:

• Word Power Made Easy by Norman Lewis
• Wren and Martin
• Reading fiction like The Alchemist, Connecting the Dots, A Brief History of Time would be useful.

Aim to learn 10 new words, their implementations, antonyms and synonyms everyday.

Quantitative Aptitude Books:

• Quantitative Aptitude for Competitive Examinations by Abhijit Guha
• Quantitative Aptitude Quantum CAT by Sarvesh Verma

Refer NCERT for all the Basic concepts.

Apart from these books, ensure to practise 2-3 mock tests DAILY.

I wish you All the very Best for CAT 2022. In case of any concerns, feel free to question again.
