Dear Ataur,

As the time approaches to the final date of CAT the way at this moment would be to get versed with how to attempt the exam in the most efficient way. 

Please brush up the basics of the exams as soon as possible and start giving mocks. Mocks are the key to sucess in CAT.

CAT exam tests the general aptitude of the candidate so the correct temprament is really crucial while attempting the exam.

Also do not delay taking mocks until the syllabus is completed as that day would never come. Just start giving mocks and analyse each one of them thouroughly and make sure you do not repeat the same mistakes again and again.

Identify your weaker sections or chapters and work on them now. Simultaneously try to enhance your skill in your stronger sections.

With correct temprament and accuracy you can surely get a good percentile in exam.
