I guess those 96% are NOT after the first time going through UWorld. If you went through UWorld several times, this cumulative score is not predictive at all. Do you remember your cumulative score before repeating the qbank? I only barely got 70%, but my NBME scores were around 240/250 afterwards. Something doesn't seem right here.
After 6 - 9 months your NBME score should be much higher. If you are going to take the exam in one month it may be around the same as your recent NBME score.
You'd need to make a new study plan and closely examine your former NBME tests: where are your weaknesses? Why couldn't you answer some of those questions correctly? Is you knowledge base still lacking (I don't think so after 6 - 9 months of prep...)? Do you have problems with your exam "stamina"? Reflect and then decide if and for how long you should postpone the exam.
