What is the ideal course duration for masters?

[ella]

How does it make a difference if my course is of 1, 1.5, or 2 years? What changes? Which is better? And why?

Hey,
Shorter course-
You'll have less time to get settled into your routine
Finishing your course might feel more hectic
You won't have as much time getting used to the experience

Longer duration-
Will make you feel more relaxed...and able to do internships and your thesis

So, it depends. If you want to finish your course as soon as possible and get a job, go for the shorter duration course.
But if it's important for you to get in-depth knowledge and experience, and you prefer a comparatively slower pace...take the one with a longer duration.
