The format of the PLQ questions is to have N quick questions in each lecture (hopefully more than one each time). You will use the PLQ app (on your phone or laptop) to submit an answer. Questions vary from short to extremely short, and the subject is either from the current lecture material or from the last one.
The goal is to have enough data to take the place of an exam as the main way of evaluating your performance. The average numbers tend to be similar to those of on exam, and having a lower average on them compared to your homework grades is very common.
Since this is effectively the exam in the class, you should treat it as such. Be prepared to answer the questions, and make sure you pay attention to your overall numbers. But do not stress about it as you do an exam.
While the PLQ is our exam substitute, making it as important as exams, do not make the mistake of stressing over it as you do for an exam. The main difference is that this is taken in tiny chunks throughout the semester. There are a few important things to learn about the format to avoid stressing about the PLQs:
And as usual, when in doubt, see me at office hours or email me to schedule a meeting. I will go over the numbers with you and give your my interpretation and impression.
For various reasons I decided to avoid exams, and the PLQ is the best substitute that I found for them. I know that it has some issues, but all other alternatives have bigger problems. If you think that you have a better alternative, feel free to email me — but keep in mind that I have been actively looking for alternatives for a long time, including asking students for ideas. (So please avoid non-solutions like using only homework.)
