Which college should I prefer: KMC, Manipal or HIMS, Dehradun for MBBS?

Without any second thoughts, choose KMC Manipal over HIMS Dehradun. Joining a private college is not considered very wise but it’s not in the case of KMC because 

• Its crowd quality is exceptionally good. It's an old college. 
• It’s one of the oldest private medical colleges and most Govt Colleges so it has come to establish a reputation of its own.
• It’s the only private medical college that has churned out so many generations of successful doctors.
• It offers excellent medical education and its fees are comparatively less than other private colleges. 
• The institute boasts of a well-equipped sports complex called MARENA.
• An amazing campus life with enough exposure to extracurricular activities. 
• The Manipal campus is extremely beautiful and offers a good academic ambiance.

Overall, the opportunities this college has to offer make it an excellent choice.
