Pros:
-You're more likely to choose a course with a particular career in mind, not just picking a random one for the sake of going to uni for the social life and to please your parents
-You're more likely to have a sensible attitude towards your work ethic, rather than a social mindset, so you may get better marks as you'll focus better and procrastinate less
Cons:
-Less socialising
-You're be entering the workforce at a much older age, making it hard to compete against younger graduates
