Colleges in Gujarat

IIM Lucknow is behind IIM Ahmedabad, Calcutta and Bangalore in rankings.

I can't say about other college but try for B.K. School of Business Management. You have good chance of getting into bk. Last year till 70 percentile students with SEBC got admission in this college. So you have a bright chance.

Take care of cut of marks of university you want to apply, you can apply through online system.

Placement stats changes every year so choose any reputed colleges.
Placement also depends on your calibre . If you perform well in academics and in interview(during companies visit).

It would totally depend on you. First of all you should identify your strong areas and your weak areas. This would only be done if you have evaluated your mock tests properly. Remember that the key to crack CAT is SPEED and ACCURACY. Hence it is important that you solve as many questions as possible correctly. And this would only come with practice. Hence in short, practice as much as you can.

u can try for 3yrs. integrated M.Tech.sys of bits -pilani
