This tactics training program should not take more than 30 minutes per session, and it is flexible enough where you can adjust the amount of puzzles and / or the amount of time spent per puzzle as well as the session time so that you can customize it to your needs and study time available.
Day 1 = 10 puzzles @ 3 minutes per puzzle
Day 2 = 10 new + 10 from day 1(d1) = 20 puzzles @ 1.5 min / puzzle
Day 3 = 10 new + 10d1 + 10d2 = 30 puzzles @ 1 min / puzzle
Day 4 = 10 new + 10d1 + 10d2 + 10d3 = 40 puzzles @ 45 sec / puzzle
Day 5 = Review previous 40 questions @ 35 sec / puzzle
Days 1-4 are the same as week 1
Day 5 Repeat 40 questions from week + include 10 random questions from the previous week for a total of 50 questions @ 35 sec/ question.
