Hello Urja.

No, taking a year gap after class 11th or even class 12th will not affect your chances to get good universities/Colleges for Ms.

M.Sc. stands for Master of Science and it is a two year postgraduate degree in specialized science fields such as Chemistry , Mathematics , Physics , Biology , Botany , Life Sciences , Bio-Technology , Microbiology and many more. Master of Science degree is designed to provide students with the required scientific knowledge and opens new and ample opportunities in a variety of fields.

Further, there are many colleges in India for MS that you can look out for after Class 12th. Some of which are :

IIT Madras

NIT, Tiruchirappalli
