Which college is better for an MBA, ITS Ghaziabad or IMS Ghaziabad?

This totally depends on the profile you are interested in. If you want to choose sales, then you should go for IMS Ghaziabad, but if you are interested in other profiles such as core finance then you should go for other better colleges like Simsree, NIBM Pune, MDI Murshidabad. You should find all the details of the college and get to know all the advantages and disadvantages of the college.

Here are some steps which will help you in choosing the right college for you.

1. You should know every detail about placements like the organization, job profile, how secure the job will be and what will be your in-hand salary. The time, money efforts you put in should be worth it and your investment shouldn't go in vain. So keep out these things clear first. 
2. Choose the area of interest of your job profile like sales, marketing, banking, core finance, and then find out which college provides your desired profile during campus placements. You should choose that particular college as this will be very beneficial for your career.
3. Do not totally depend on the rankings of a college as it doesn't tell the whole story of a college. Do check by yourself by chatting with college alumni or visit the campus if possible to find out the exact picture of the college environment and placement records.
4. If you want to get into a finance job profile, then score 55-60% marks minimum and a higher CAT score, as it's required by most of the top colleges. For a core marketing profile too, you should score higher in your entrance exams. Even it can reduce your fees in top government colleges by around 1.6L.
5. Do not fall for annual CTC packages offered by the companies. Always look for the actual in-hand salary you will receive as it is much less than the annual package offered to you. This is very important and ignoring this will may lead you to trouble while repaying your educational loans if taken. 
6. If you want to become a commercial bank manager or an IT manager but you're coerced to banking or IT field sales, then you should find out whether the job profile is suitable for you or not. 

Following all these steps you can do proper research about the colleges and then find out the one which will be best for you according to your requirements.
