Hi Sherif and Annie,
It's good to have company. I have failed twice and was going to give up after the January change; but, as the saying goes, "third's a charm".
Some folks are better CBT test takers, some people get short ?'s on the PMP. Both times I had very long paragraphs and a lot of formula and critical path diagrams to draw. Sometimes test nerves take over. There can be a lot of factors.
Since you used Fast Track and took PrepCast twice, you were beginning to get repeat questions. My only advice would be to review missed and correct questions, understand
exactly what was right and what wasn't and why.
On a different note; I had to pass 7 exams to become a licensed Architect. I passed 2 of 7 1st time, 3 of 7 the 2nd time, 1@3X and the last one 4X.

Take a breather, dust yourself off and, as Annie said, if you want it...Go for it and don't look back!

All my kindest wishes and best of luck.
Debby
