CAT Preparation

Allthough time for CAT is near, coaching and concentrated preparation will definately help to improve your chances to score good percentile.

Nothing is enough, but solving countless mock tests give you practical knowledge about CAT. It will help you to understand the exam type, and help you to manage time and increase your accuracy, but if you are confident enough about your ability, then you can go ahead with your plan. It is a very difficult task.
All the best.

You can refer to CAT by Arun Sharma. It is a very useful, simple and is having an easy to understand language.

No, it doesn't matter to which field you belong. For CAT, minimum 4-5 months are required to score well.
All the best.

In case you have excellent verbal and numerical ability developed over the years in your basic schooling and graduation, you can prepare for CAT in 2 months easily.

It will be a little difficult as the competition is very high and the level of questions is rising year by year. You need very clear and good conceptual knowledge about all the sections to clear it. But don't loose heart. I have seen people preparing for 3 months and getting into IIMs. Do prepare hard in these 2-3 months and you might be able to crack it. All the best.

You can opt for any of them. Your hard work and problem-solving skills will help you in qualifying CAT exam. According to me, TIME is a better coaching institute as its practice material helps you to get acclimatize with the types of questions asked in CAT exam.

Two months is not very long time but with good efforts, you can definitely crack it. You just need to practice more and more and have to focus on your weak areas.

You should opt for IMS. Its curriculum and teaching methods are more beneficial than that of TIME, and Career Launcher.
