As a grad student in CS, for theoretical and algorithmic courses, doing the proofs one by one is the only thing that works for me on how to get a good understanding of what tools the proof provides for me, what new pattern of solving a problem exists and making use of it. I found that it significantly expands my repertoir, or grammar and vocabulary so to speak instead of staring at the lecturer trying to explain their thought process.
