Alliance

IBS is better than Alliance. Alliance and IBS are very top class campuses which offer MBA education with perfection.
ICFAI IBS is very good in terms of education as well as placements.
Placements last year the package approximately went to an average of 6.9 lakhs.
95% of students who did MBA from ICFAI are getting good salary packages.
International placement in one batch is approximately 25% which indicates their strength in international tie-ups.
They are giving enough opportunities in India and abroad. The quality of education is also very good. Live case study based education help them develop industry knowledge and the students are getting easily adapted to the multinational and corporate mindset.
But Alliance school offers a less salary scale in the range of 4 to 10 lakhs per annum. The international relations of Alliance is less than IBS. So, I suggest IBS rather than Alliance.

In Bangalore you should give first preference to Christ University for BBA, if not you can consider Alliance University. There are many Bangalore University affiliated colleges, also Mount Carmel (only for girls) (Autonomous), St Josephs, Kristu Jayanti, Presidency, etc. But still Alliance is on the path of success and gaining market value. This is the best university in India for BBA, the teachers are so good that you would learn everything in three years and there is no need to do MBA too, until you need an additional certificate. I accept that the college is located in a village, but Anekal is slowly developing. The environment around the college is so good, that you should not have a second thought of joining here.

MIT Arts, Commerce and Science College and Alliance School of Business are equally good. Some of the important points while selecting an institute - Accreditation of the institute, institute's infrastructure, teaching faculty, specialization offered, past placements records., tuition fees, city preference and industry interface. As both the institutes are having the campus in Bangalore and Pune. Industry exposure is good for students in either of the college. If possible a visit to college is better option to get a reality check. Also, get in touch with college alumni's through the social network to get information about the latest changes if any.
You can compare the course fee, placements, students review, facilities offered and seats-

I know that your life will be doomed in Ramaiah Institute of Management studies. Please don't fall into the trap.
Nothing is good about this MBA College.
MS Ramaiah is a very good college.
RIMS just uses the same brand name, that is all.
Most people think that MS Ramaiah and RIMS is the same.
But, it is not the truth .
RIMS is way out of the main campus , and is under MS Ramaiah foundation. They promise good placement, but none of their promise are met at the end.
Same is for Ramaiah Institute of Business Studies (RIBS ) and Ramaiah Institute of Legal Studies (RILS)
These are not the same as MS Ramaiah.
They lie about the placement and everything.
They are very money minded people.
Poor infrastructure and management
Requires 90% attendance, otherwise Rs. 10000 fine.
Uniform is made of synthetic.
If you are late by 2 mins in class, you don't get attendance.
Teacher will confiscate your phone, if seen using anywhere inside the campus.
No fashion trends, like coloring hair or making bun or having Beard etc. is allowed.
It is a horrible college. Please don't join.
