Yes, a simple interface for schools/teachers to upload their exam schedules, for any school anywhere, would be an ideal use for this name. Too bad the singular is taken (even though the plural makes more sense for the use of the name).
But it's a valuable service, and if dev'd right would get a lot of traffic to your site since it's that demographic that uses the net so much. IMO very worthwhile to put a little time and $ into some even simple development along these lines, with a little hip art to make it more attractive to the student bodies. I think the resultant traffic would make it well worth the effort, especially since it's such a clear name with a no-brainer meaning; anyone looking at it would know exactly what the inside content would/should be.
Undeveloped - clear meaning, valuable usage to a large and relevant market, and large potential for making nice ancilliary traffic income from related adsense and possibly sponsors on the site, so I'll give it a healthy estimate of around
mid to high xxx for resellers and end users alike, more of course if they really want to run with it. I'm only giving it a high value because it has such a clear meaning and memorability; but there are a lot of similar names still left at reg fee, and a lot of extensions still available for all of these (including yours) so that I wouldn't ask too high a price for this one... easy to grab examTimes.net for reg fee and develop the heck out of it for minimal cash, than to use up all that budget simply buying the dot.com.
But I think you'd see a lot more success with it, and provide a nice service, with a little dev'ing.
Nice name, good grab.
