IIM Lucknow - Indian Institute of Management

Yes, but if you are just targeting he cut-offs, then you'll get calls only from new IIMs.

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

Chances are high, but you shall be needing a good GDPI score and keep your graduation average score at above 75%. High cgances of converting IIMs, but you should be well versed with current affairs and management knowledge.

The cut-off details have not been released yet. Please refer various mba sites for the previous years cut-off. If you are aiming to appear for CAT this October, then I think it's high time to start preparation. Improve your reading and writing skills, apart from communication skills. Apart from the usual CAT course preparation that you have to do by default, go through newspapers, articles of your interest everyday. Work on your speed, mock CAT exams can help.

Yes, the marks are seen and sometimes part of evaluation criteria too. Depends from IIM to IIM

To get through IIM A B C & L . you'll need 99% percentile, apart from fair enough grades in graduation and schooling. For other IIMs too, you will need at least 97% percentile (note, percentile is different from percentage)

IIM Lucknow. It's not the best, but should be better than st. Xavier in terms of various parameters. Although both the colleges are, I'm sure, well-equipped with all necessary facilities, etc. Faculty and placements at IIM Lucknow are better.
Having said that, its not harmful to take advise from St.Xavier's student as well.

It is difficult to compare as one cannot personally know both colleges very well. I can give you some insights about IIM Lucknow, though.
Campus- The campus is beautiful, with every possible amenity that would be required. Huge library, spacious rooms, gym, swimming pool, sports ground/court, etc.
Food- IIM Lucknow mess food is good. I think you can compare any college's food with ours and we will win for sure!
Academics- No doubt IIM Lucknow is better.
Placements- Again, there is no match!
Probably, your field of interest might help you compare the two colleges. Taking opinions from any student of SP JIMR might help as well.

As of now, you must focus on your studies and get good grades, while you are doing your under-graduation. For CAT prep, make reading books, news, article as a daily habit. Also keep a good command over your communication skills, if you feel there is scope for it. I think this will do as of now. You may take up CAT class later on.

Sorry! With such scores, it is not possible. However, do try other good MBA colleges.
