Good question, John! I talk a little bit about this in Module 10 of the course (lesson 10.5), but my general recommendation is about 50/50. Half the time should go into studying something and the other half playing. Ideally I would go through the course videos until you have a few “aha” moments, and then play a few games and try to implement those ideas in the games. Then back to the course, and repeat. Regarding the puzzles, you’ll get a lot of practice with those in Module 4, so I would put that on hold until you finish the course, and then pick those back up again after the course is completed. Analyzing games afterwards is a good habit, but it’s also very time consuming so if you don’t have the extra time for it you could save that for particularly “confusing” games where you don’t know where you went wrong. Hope that makes sense!
