Personally I believe everything happens for a reason. When you have your metaphorical cup of tea have a think about why this has happened, what the universe is trying to teach you.
If it involves someone else, perhaps ask yourself if the lesson is for them instead/as well?
Once you have figured out the why, you can move on and learn from your experience, perhaps this hiccup is to show you that you have taken your academic position for granted, or perhaps to teach your tutor to slow down and take time to really think about how they are teaching...
There is some great advice here, just remember life is a journey, not a race... all is zen
