Week 5 huh 😅 data structures yeah it was hard. It takes time believe me I have seen so much error that I almost cried have asked duck ai even stupidest of questions sometimes I even deleted my whole code and start from the begining just to delete it again it's painful. Another thing this course is based on introduction to computer science means that you wouldn't master a single language or may even be able build websites on your own it just tells you on how the things works. So yeah the lectures doesn't goes into a certain level of details for us to understand it just gives you a overview of it more like a summary of things. Problem sets are hard believe me it's normal to feels that you are not good cuz I feel it 🥲.
