Hey Souradip

I will compare both these courses for you.

Firstly, KIIT will not provide any placements for you in BDS course. So you will have to arrange your own means to work in a hospital or open a clinic of your own. For BSc Nursing there is a placement cell and  Appolo, AMRI, PBHM, etc. visit to offer jobs. So, if you have connections or money to open your own clinic without any doubt you should go for BDS but if you come from a humble family choosing nursing will be a better option.

Secondly,  BDS is a 4.5 years course + 1 year compulsory internship. The faculty in BDS is good butthe subject is difficult and requires a lot of studying and hardwork. BSc nursing will take 4 years in total and the faculty for this course is good too. If you go wth the time thing then bsc nursing will get you a job in lesser time whereas bds will take atlease 5.5 years of your life.

All the best.
