Is JEE Coaching helpful for atleast qualifying an entrance exam for MBA?

No,the two fields are extremely different one is purely Technical and other is business admistrative.

No not yet, those are ekdm different fields.. So preparation v alag hota hein uska.. & jee ka toh preparation b tech k liye hota hein, magar MBA will be after graduation.. So all different..

Maybe for QA but for others sections, I don't think so especially for RC/VA, your need to have a long term strategy which I won't deny unless you are comfortable with RC/VA...Now coming back to your query, I believe it is upon you to recognize your strengths and weaknesses and then to work upon those, but I would suggest to never over-estimate your talent or your skills and to work upon those until you achieve what you desire...once you achieve those you will be the happiest or you will work towards to improve it...consider it as your win or an opportunity to improve your skills, so chill and work your way through...I hope this answer helps you

No definitely not.you can't compare these two exams..... IITJEE is a exam conducted for admission into undergraduate courses while CAT (for MBA) is conducted for admission into postgraduate courses...... just google it!

No not at all. How can you compare the IIT -JEE exam preparations with CAT exam because both of them are entirely different. IIT-JEE is an entrance exam for best engineering colleges in India whereas CAT exam is to get admission in the best B-schools in India.

In JEE preparations you are taught all about physics, chemistry and Maths because that is been asked in the IIT-JEE whereas in CAT exam you are asked about quantitative ability, verbal ability, data interpretation and logical reasoning.

So what you learn in JEE preparations wontbhelp you at all for your CAT exam. You need to take different coachings for CAT like in TIME, Career Launcher etc.
Also you will need to attempt lots of online mock test because CAT exam is an entirely 1exam if speed with accuracy.
