(?) I know there are various ways to do this, they just escape me at the moment.
If you want to make it more "fair" consider bining the questions by difficulty and randomly select some number from each bin, versus a random selection / generation over the entire pool of possible questions, or actually timing each response individually and showing an average of the percentiles for each answer, instead of a percentile for the average time.
Total sums done: 3,816,583 -- really?
For the timer, can it be a non-decimal number? Seems like I don't really care about decimal time (don't think most users care about fractions of a second)
But that aside, this is nicely done.
Can you make a large bank of harder questions?
