The waiting for exam results is often very consuming. If they are going to be posted on the webpage of the course you are probably refreshing the page every hour for sometimes a long time. I can remember one exam, where the expected publication was unknown and took nearly two months. The exam has been corrected on the same day by the assistants ,and this was known to us, but for some reason the publication has been delayed. Since the nervous refreshing is very bad for your health it would be better to let your computer look for updates and tell you if the results are available.
Finding a tool that is able to control all updates if they really contain the results is actually not that easy, but for being notified for all updates is. Since it is very likely that if the website is getting updated, it really contains the results, we should be satisfied with that. A simple tool for that is the Firefox-Addon Update Scanner.
Chosing a page to be scanned for update is very easy. You only have to visit the page, do a right-click and chose the entry ‚Scan Page For Updates…‘ . Afterwards you define a limit for symbols being ignored (such as if the webpage prints dynamically the actual date). If there is no dynamic content you should disable this function, so you wont miss an update.
After you have configured the scanner for the page you can lean back and wait for your results. If the page has been updated you will see the notification from above and the page will be opened with the changes highlighted in yellow.
For other browser there are similar extensions.
