What should I go for, K J SIMSR full-time PGDM or IMT-Ghaziabad DCP?

In terms of the brand, you must go for IMT as K J SIMSR stands nowhere near to in comparison to IMT.

Other than the brand, the following are certainly other characters that make it very much necessary to make you think over the other options you have:

• There lies a broad difference among those who completed their first year on the Ghaziabad campus and at Dubai Campus. As the exposure at Ghaziabad is way better related to Dubai Campus. You need to be very hard-working, great at networking as being at DCP campus, you will find networking becomes more important to land a good summer placement.
• The second-year brings you a lot more opportunities to do networking, study with better companions, get exposure to far better resources and faculties compared to Dubai Campus. DCP is a way of opportunity for you to be in a group of such a premier B-school at the Ghaziabad campus.

• Be ready to begin your A-game when you join the Ghaziabad campus. If things work out great and you are invariably aware of the above two points. 
• During your final placement season, opportunities are similar to those of that student who has spent their first two years at IMT Ghaziabad campus provided that in the second year, you complete a better crowd and your 10th, 12th, Graduation percentage are in good shape in order to increase your chances exponentially in the 2nd year when you join the campus.

Ultimately your decision lies in your hands. If u keep considering the brand value and the above aspects in your mind, then you must opt for IMT Ghaziabad DCP else if you want to play the safer game, then definitely, forget about these aspects, and go for KJSOM.
