Hello Yi Qian Ye. Thank you for your response. I think that it's good to take this course no matter what. UX is a lot about ongoing learning, and it's important to understand the tools and concepts that UX is using.
I attended many UX classes and courses before taking this Google Coursera course, and I feel that it is very important to me to keep learning and also practicing what I'm learning.
Also, I think that you will get the most out of doing the assigned projects, so I would focus on doing the projects and the design thinking for the projects. That's really important for building a portfolio.
That said, I'm not sure how you do the class without peer review, which is Coursera's way of providing the 'passed/finished the assignment' badge. But keep learning, no matter what.
I hope this will help you in your UX future!
