With books that teach a language or advanced stuff about a language, like, say, C# in Depth, I read from start to finish, without actually doing any exercises or really anything else. I trust my memory enough to rely on remembering that "C# in Depth was talking about this thing", when I run into something IRL. Then I go back to the book and see what it had to say.
