IILM and NDIM come under the same league. The table given below shows a detailed overview of the institutes:

Some of the factors to keep in mind while choosing a B-School are discussed below.

• Both these colleges are average. If you have a good MAT score of above 95 you can choose a better B-School. Some tier I management institutes accept MAT scores, try to secure a seat at these institutes. You can get admission to good B-Schools through CAT too.

• Simsree Mumbai Govt of MH and  Pumba Pune university are reputed management institutes with affordable fee range and higher ROI. 
• Bimtech Noida is another good alternative with smaller batch size. XIME, Christ Bangalore, Great lakes Chennai are also reputed management institutes.
• Don’t choose a university, based on the 100% placement rate, annual CTC, or ranking. Contact alumni of the institutes on Linkedin to know about the job stability. 
• You have two options, score better in CAT (>80) and choose a reputed B-School that offers placement with a good in-hand salary or if you are choosing a B-School based on MAT score, do your own research and choose the right one. 
• Most colleges reveal the annual package offered in placement, not the in-hand salary. Always check the in-hand salary offered before choosing an institute. Some colleges give the assurance of 100% placement, but the job profiles offered may not be sustainable. Some colleges also offer mass recruitment for placement. So, do your own research well before investing in your management degree.

Do be fooled by the ‘first come, first serve’ policy that some management institute uses for marketing. Tier 1 institutes do not need such marketing strategies. The quality of education of these institutes is enough to build their reputation. So, do some research about the institutes and choose wisely.
