It's a fantastic app, I have been able to prepare the test and send it to the students 2-3 days in advance. When a student clicks on the link he/she can see a back counting clock saying that the test starts in 48 hours or something like that as per the settings. So, I get freed up on the scheduled time of the test and utilize the time for doing some other work/travelling etc.... That adds to our productivity. Besides that it can be customized as per one's desire as adding a logo of your own. The feature to download the all the details of exam as an excel file is also great. Overall, a satisfying experience.
