I have completed uploading all the lectures for every part. How did you find the course? Project 2 must have been quite tight, and especially in Project 3, as you naturally used what you learned + additional concepts unfolded, the parts where you looked back and reviewed what came before probably gradually decreased.
Since everyone will experience different levels of difficulty, I expect that some of you will naturally have questions that haven't been resolved, or parts that seem to have been glossed over in the lectures. Feel free to leave questions on Inflearn, or you can leave them in the 'Course Questions' tab at this Discord link https://discord.gg/juEUX2Wv where I check more frequently and can respond faster. Please let me know where you're stuck. I believe it's also the instructor's role to tell you 'just move forward for now.' Great work, everyone.
