I've been hacking away at the adding and subtracting fractions exercise, when I noticed that the progress bar wasn't moving as quickly as it should- so I decided to start taking a tally of how many questions I'd done in a row. I've already done ten, and the bar is only halfway. The 'focus' section on my profile won't show up, either.
