Anon,
It's upsetting to not have done as well as you had hoped in the exam, but it's great that you have passed overall : )
It might be worthwhile to find out more about the exam and where you lost marks, in case there are areas to learn from this year, but after that try to put it behind you.
You don't want to be carrying last year into this year, when you have new modules to focus on.
Try and improve your exam technique if it's something like time management, answering the question fully, or reading the question carefully, but then move on.
All the best,
