If you started the course from scratch and you just finished it, then you can just ignore this. Congratulations again!

But if you were following the old version of the course (before 2025), and if you still want to access the old content, then you can find the old course videos in this youtube playlist: https://www.youtube.com/playlist?list=PLLSegLrePWgJQOwu2gzQyZdWGOKB0dOdW

Note: the old content is already obsolete and will not be updated. I'm just uploading this as people requested it, to make the transition smoother between the old and new version of the course.
