You're absolutely right. I know in 20 years I'll look back and be like "meh, I delayed starting university by 2 years instead of 1".
I think my parents will be fine with it because they want me to do what I want to and not just do something for the sake of it.
My issue is that it's another year. A year feels like a long time. I'm only 3 days into this course so far and if I reapply and get in it means I'll be starting university in October 2018.
That's over a year away. At which point I'll have completed 1/3 of a degree.
Perhaps I should apply, if I get in I can accept and then decide whether or not I want to start a different course or continue the one I'm on (computer science).
