I usually try to go through the whole thing quickly in a weekend (usually skipping exercises unless I'm not sure I understood something correctly). This allows me to get rid of a chunk of my "unkown unkowns" (e.g. if I ever face a problem related to the topic, I will know a solution exists). I will sometime do a more in depth study a few months or even years later if the topic truly interests me or if I need the knowledge for a specific problem I'm trying to solve. (see just-in-time vs. just-in-case learning for pros and cons)
If I really want to master the topic, I will try to only study a few hours a week and do the exercises, but I rarely get the discipline required.
