This is a difficult one for sure.  Overall I think you are probably doing what is best for both of you at the moment by waiting.  While it may suck a bit for you, especially with moving on, you are also showing a lot of maturity and honor.

1)  You came to ask for honest advice, knowing it was a hard issue and wanting to do it the right way

2)  You are mostly thinking about her in this instance and how it may affect her personally and professionally

3)  You are still being committed to the relationship in many ways until it is officially over (not seeing anyone else, not sleeping or even looking)

Overall I believe you are probably doing what is best here.

My *only* caveat is something you have somewhat addressed in here a bit.  And that is the level of support change.  If you were fine with it before, and now things have changed, if they were to go back to the same levels of before after her exam, would that change your mind?  It seems her lack of support may have ties to her education and career choice.  Also her lack of support for your dream job seems due more to the distance and not having as much time together, which seems to be the case since you say a lot of that has stopped.  It sounds like that is likely due to both your job being far away and a ramp up to her studying for the big exam.  

That being said, I don't think anyone should stay in an unbalanced relationship and if it was really unbalanced from the start it sounds like you may not have made the wisest choice to move in initially.  But relationships are often about experience and learning, and that seems to be what you are getting here.  And as I said, I think you are doing what you think is best and it generally seems to be the right way about it.
