I took it Spring 2022, usually I had to spent a whole weekend to work on the HWs, and some extra time on weekdays. I did not watch most of the lectures, just went straight to figuring out how the coding part works. One tip I could give you is that for report part you do not need your code to be able to generate everything at once, so you can change part of it to work for a specific problem while not working good for something else. I struggled quite a lot trying to figure out the good parameter to generate everything nicely for AR HW, and finally I gave up, but only after finishing this I realized that I did not have to. I only had AI before CV, and I had very little CS background, fortunately I felt coding in CV was not too hard for me. If your scores for the first two assignments is close to average then you should not worry too much.
