I did Phys1160 for my last semester last year and TBH even though it was a very easy course but the workload involved was actually quite significant.
I remember you have to regularly post things on the forum to earn marks for entire semester and there were many essays to do. There were online quizs for sure since it's online course but they're not as easy as I thought.
I admitted this course was easy but I absolutely hated the assessments involved.
