It was announced on the first day of class that you should buy the Launchpad and install CCS. It was also covered in many screencasts. You should have been practicing CCS as the class was going on and emailing me or the TAs if you had any problems during the week (not on weekends please). Yet many of you bought the Launchpad and installed CCS at the last moment and many of you are having problems. There are 150 students in this class. I and the TAs are being overwhelmed by emails by students on a weekend on the last day of quiz submission. Each debugging session takes roughly five to ten emails before the problem is resolved by email. So unless you have a really good excuse for being so late in doing your stuff please stop emailing us and set up a Zoom meeting with Han next week, and then submit your quiz02 late for a 20% penalty. Thanks!
