The S2N method is a nice generic study plan for people who need an outline of how to study, but it felt too slow to me and I was getting frustrated, so I did my own thing.
I study whenever I feel motivated. Some days this is 12 hours of focused reading and practice problems, some days it is just some random skimming of my notes.
When I was doing content review, it was usually ~10 hours per day on study days(2 chapters+practice problems) and ~3 hours on break days. That took about a month. Now that I have started practice exams and been very happy with the results, I am in "hope I don't forget stuff between now and my test" mode.
