Hi Upender,

Coaching certainly helps in getting professional guidance and analysing your performance in mock tests. However, there is no set rule of taking coaching for CAT preparations. There are many students who prepare for CAT by self-study and score really well in the exam. You need to see where you stand in terms of preparation as far as CAT is concerned. Depending on that, you can decide whether you want to do self-study or coaching. 

TIME is a renowned MBA coaching institute and you will certainly get a benefit of coaching. To get CAT preparation tips from toppers and academic experts, visit -
