It has the advantage of being able to learn CS core knowledge in a short period of time. However, even if the lecture material is updated, I would appreciate it if you could adjust the content on each page so that it does not change significantly. After seeing the recent update notice, I tried to change only the pages that GoodNotes told me to, but due to the modification, the following pages were also pushed back, so the content on each page was different from the previous one, so I had to change all the following pages and readjust the note positions.ㅠㅠ I am satisfied with the lecture quality!
