A question that is there in every aspirant, what is the right time to start preparing for MBA .
Guys according to me preparation starts long back when we all start building our interest in reading story books, then jump on to news papers, novels etc. as once u start reading u happen to come across so many new words that u start looking for it in the dictionary, so in this whole process u unknowingly start building a good database of words and also start using it in day- to - day life.
When u land up in the college, u have goals set and thats the ideal time to put all ur past knowledge to work.
Start preparing in a very routine way so that it it is imbibed in your schedule and u really not need to put any extra effort for the so called preparation .
You should be doing a good amount of reading from newspapers, magazines so that u r updated and novels which u can say for as one of ur hobbies.
Start doing some mathematics , ana, LR, DS etc from a simple book to start with like RS Aggrawal then once u r comfortable u can move ahead n pick real tough stuff.
My advice wud be do it without the help of pen n paper so then ur speed wud enhance tremendously.
Once into third yr of ur graduation(engg) join a good coaching institute just for the feel of competitive environment which wud help u building a tempo and unearth ur mistakes and also bring certain new methods of doing things( short cuts minimum efforts max result)
This what I had done during my engg. and ultimately landed up doing my MBA from Symbiosis .
Hope it helps u guys.
All the best.
