At RPI (Rensselaer Polytechnic Institute), it seems inevitable that you will come across a course you want to take and then be left in dismay when you notice that all the slots are taken. The good thing is, students do drop courses with time. However, you’re then competing with everyone else that wants the slot in question. To give you the edge, I developed a tool to send you a text message within a few minutes of someone dropping a course. So let’s walk through how it works.
Say you want to take the course “Speech Communication”. If you don’t care which section, this would be your message “watch writ2340″. The second word represents the department and course number. If you do care about the section, you send the word “watch” with the crn. For this particular course, a target crn is 97962. Your message would be “watch 97962″. Get it?
Send that message to N/A.
What if you want to remove a particular watch? Just send the watch message to that number, with “kill” substituted for “watch”.
