Frank Marian, Australia

I retired last September from Australian Dept. of Defence after 46 years’ service as a Defence Scientist. Never been busier need many more hours in my day.

Have over the years particularly when gone to sea loved doing the Sudoku puzzles when not on the bridge of the ship. Not a fan of TV it’s such a waste of time. Nothing better than getting a bit of quite time, and doing a Sudoku. I am a bit bloody minded a have spent many hours on the one puzzle. I am very proud of myself when I get one completed.

Have loved working with you on your videos, pause the video all the time. Have completed the extra work sheets given. The idea I like most is your pencil marking techniques. I just saves so much time not having to remember what possible numbers could fit in a square. Have completed most of your extra sheets in about one hour to hour and a half.

Navy is asking for my help, wanting me to come back to work, go on a six week sea trial June/ July so will being down loading the more advanced lessons to my lap top and taking them away with me.
