Dear Chad, I am a subscriber to your on line videos, and after 2 weeks, I finished viewing and working the Freshman and Sophomore Videos/puzzles. I just wanted to tell you how pleased I am with your presentation method and the progress I am personally making solving the sudoku puzzles. Nothing that I have tried up to now has been as effective as your videos and working through the puzzles with you on the videos. Now, I am solving moderate puzzles with good success where I couldn’t even solve them before. Your techniques are the greatest and I look forward to continuing through the junior and senior puzzles. Thank you so much for making your videos available. Regards,
