There will be NEW exam one week later. Unless you are all below target from all domains from exam simulator, I would suggest try your best to take the exam this year.
Review carefully the explanations for the wrong answers. Pay more attention to the questions for Change Control, Problem Stakeholders, Communications, Issues, Risks. There are a lot of questions on those categories, after reviewing the explanations, make your own conclusions for exam. Always think from a big picture, not just your own working experience.
Good luck!
