The wild world of course registration heats up during the last round of selection, where occasionally seats are released due to dropouts and the remaining dash for the vacancy. But what if I told you there’s a clever way to outsmart the system? No more frantic refreshing, here’s nifty little program I concocted that plays the waiting game for you. It keeps an eagle eye on course availability and sends you an email the moment a spot opens up.
Remarks: required packages are all common packages available online, and can be conveniently installed using pip or conda anyway. Still, the version of Chromedriver and Chrome needs to pay extra attention. Also, one might need to adjust the login-click target xpaths based on the website logic, since it’s a simulation of human actions.
