By the way, @jaejun02, I just realized that you were asking questions about the MLS but, in my last reply, I was quoting lectures from the DLS.
So, I would like to share two ways you can have free access to them:
- enroll and audit DLS’s course 3 ← this is up to date.
- check out this playlist
Even though they are DLS course 3 lectures, they don’t really require knowledge from course 1 & 2, so you might choose to watch them as supplementary for your MLS journey.
Cheers,
Raymond
