When taking your HSC -- or what ever the relevant government is calling it these days -- the last thing you want is your university dreams dashed because you ran out of time. So for $US40 this Testing Timer watch has a very specific purpose -- keeping you on time and on pace to finish every question in the allotted time frame.
Designed as specific versions for standardised SAT tests in the US, the watches feature various indicators and countdown timers that let the testee know how much time they've got for a given section, and the overall exam. A simple set of control buttons let's the user jump around from section to section, and the watch meets with all the criteria (at least in the US, anyway) so it can actually be worn in the testing room -- not just during preparations. Staying on top of the time and your progress is definitely a great idea, but having a constant reminder to hurry up sounds even more stressful than that annoying final Jeopardy jingle.
