It depends on how rigorous/detailed you want to be. This is at most two semesters worth of material, and has a very shallow learning curve (hence the large PDF). If you've been exposed to these ideas, you could cover it in a semester. I'd say it's quite doable in a year in your spare time.

If you drop the combinatorics chapter, it is definitely doable in one semester.

For example, Chapter 7 is 100 pages. In Tao's analysis book, he covers the same material in 42 pages.
