Bit by bit I'm chipping away at the 1000 tactical chunk.
After going back to problems 1-110 and from 111-200, I've found that I need to review these problems regularly. So I've incorporated a review in each session. This chews into my CTS time, but CT-ART is the primary focus, so I'm not too concerned about missing out on CTS problems.
CT-ART: 1-110, 142-172, 201-280
CTS: 23 (1223)
For CT-ART, I'm taking 10 to 15 minutes to review 1-110. Next I take a chunk of 30 from the 111-200 range. Lastly I work on 201 up to the point of memorization ... so tonight I went up to 280. The whole cycle takes about an hour. It's amazing how I just do the problems without much thought. Tonight I went into "new" territory without knowing and I just hummed right along without missing a beat. It must be working.
