I hesitated before purchasing because the lecture price was high, but I think I made a good purchase because the content of part 2 is really informative. GSAP plugins, methods, callbacks, etc. are basic, and the examples and sources provided as practice materials seem to have a lot to use. And after completing it once, I am both happy and worried about how much practice I will need to do to properly utilize what I learned here. I am also looking forward to the next Scroll Trigger lecture.
