Sorry to hear.
However, I suggest you retake the exam after focusing on studying/ concepts (rather than doing more mock-ups).
I would recommend you to type all the ITTOs of one knowledge area in an A3 sheet and manually draw lines (using different highlighter)from outputs of each process to where it is going as an input to another process in the same knowledge area.
For example - if you print "Integration" knowledge area in one sheet - all 5 process (from initiating to closing) & their ITTOs will be available in the same page. Once you start drawing/ linking the outputs to inputs you will get a better understanding of the concept and this visual picture will remain in your mind.
Another thing is to prioritize which knowledge areas you need focus on -
(I followed below, but you may follow based on which areas you achieved below targets)
1. Integration, 2. Procurement, 3. Stakeholder management (because "Initiating" only comes in 1&3, "Closing" only comes in 1&2)
4. HR, 5.Quality, 6.Time, 7.Scope
8.Risk, 9.Cost, 10. Communications
Good luck!
