Can someone explain how these class work?

I've heard that PSYCH 1X03 is online and there's a weekly quiz every Friday.
If that's the case why is there a building name and room number in my schedule?

Also, does PSYCH 1XX3 have weekly quizzes too?

For both courses, there are online modules that you must watch every week, an hour long tutorial that you attend (at the building and room number on your schedule), and an online quiz every Friday on what you learned that week in tutorial and the modules. The only difference for PSYCH 1XX3 is that it also has a one hour live lecture each week, where your prof will discuss more content from that week's topic.
