Team, I would like to understand the PMP online exam features wherein we can review the difficult question later, strike off available options which are not relevant etc. I came to know that these features would be helpful in tagging the difficult question s for later review. Also heard from PMP passed guys that there will be four features provided at the top of online exam screen, one of which say "Review later" other one has few color tabs and rest unable to get any info. Tried to get the online exam screen from search engine but of no use.
