CFA- Guidance

First off, congrats to those that passed level 3 of the CFA (the email came out this morning). I'm not in that boat.

I guess this post will be part rant part I need help. I passed levels 1 and 2 and went on to fail level 3 in August. I studied over 300 hours and felt like I had a strong grasp of the material so I can only assume I bombed the free response. To those of you that did pass how did you study? I felt like I studied well but I guess I graded my free responses too easily. Does anyone have any good tutors that I could work with to ensure I'm grading accurately and they can help me with the final points?

Secondly, any idea how to get motivated again? The last 3 months while it was being graded I really felt I had a strong chance of passing but now I'm sad, pissed, and agonizing over the next 6 months. I'm probably just being a child, but I remember how much it took from me for each exam and I'm not looking forward to it.. at all.

Any other guidance would be great.
