Several years ago, I found this course schedule from Cambridge. I also found some synopses from Oxford here$$. They have been very useful because they contain complete course guides, for example (Cambridge):
Notice that it is very detailed, it has the total number of lectures, the number inside brackets is the (approximate) number of lectures to finish the contents in each paragraph. There are also very good book recomendations with a cross to mark some book which is particularly fit for the course.
Aside from that, the only other material I found that looks similar is Garrity's All the Mathematics You Missed: But Need to Know for Graduate School, it doesn't have all the details but it has a nice conversation about the subjects. I also found the following website: How to Become a Pure Mathematician (or Statistician).
I found these guides to be extremely useful.
Do you know more universities that provide such useful syllabi/synopses/schedules? I have been looking for some time, but it seems that Oxford/Cambridge is really unique with respect to this: Some of them just give the name of one book and doesn't detail it, other may have something like this but it's restricted for official students.
Do you know other books/websites/etc such as the ones I mentioned?
$:$ I am a bit confused by the bureaucratic usage of the words "syllabus", "synopses", "schedules", etc. When I first searched for it, the name of the document was "syllabus", now it is "schedule".
