Ive got my upgrade soon and Im feeling so unconfident. Everyone keeps telling me how its a great opportunity to assess your progress and direction and make sure you are on track in the long-term. And that its just a formality. But so far my experience has already led to submitting my upgrade, having a meeting, having to re-write and re-submit. And now I have another meeting because there are still 'concerns'. I dont know what else they want from me. Any advice?!
