I cannot find any info on how long the tests last, how many questions, and mostly am wondering if they can be paused and resumed later like the other tests? thanks!

The assessments are 100 questions and you get at least 2.5hrs maybe 3hrs to complete it. You can pause/suspend to come back and finish it later like the other tests. There is a countdown timer so if you don't pause it and just leave it open, you'll run out of time. Once you start it, it will be available for 2 weeks total. So like if you start it then pause it multiple times and finish it by day 4, you'll have 10 days left to review it.
