• To get a job: a better job, to pass through a gate towards a graduate job, as a springboard to a job.
• To gain a qualification: as above, though sometimes it is primarily a badge of honour and achievement
• To feed your curiosity: a compulsion or desire to better understand a think for the pure sake of learning.
• To renew a long held interest that may have started at school or with a first degree.
• Because it is expected of you: your family and peers expect it.
• To develop fluency in the subject for whatever reason - which includes some of those above.
• To apply your learning directly to a problem : can be related to a job, research or intellectual curiosity.
• To kill time: like reading a book, doing Sudoko puzzles or watching Soaps. A pricey way to fill part of your day though?
• To meet like-minded people.
• As a catalyst to who knows what.
