Unfortunately I couldn't participate to Mock Test 13 but I will print the puzzles and try them anyway. It seems that they were pretty tough, and pretty nice too. Let's see !

I finally had time to finish grids of the 13th mocktest. Grids were beautiful and hard. During the test, I managed 4 grids: even product frame, consecutive sum frame, Outside antiknight and Sequences equal sum. I made stupid mistakes on end of odd even no touch and extra-region quadro.

I made other grids this week. I found non-consecutive numeral, odd multiplication table and irregular kropki very tough, perhaps more difficult than surprise and sequences equal sum, which brought yet more points...

I found that grids of the booklet were a little too easy compared to the grid test.

Otherwise, I congratulate Rohan and Tejal for these fine grids.

Thanks Fred, I really appreciate your comments.
After all the feedback we've received, Tejal and I agree that Odd Multiplication Table was tough and deserved more points. Irregular Kropki is a 3 minute puzzle once you get the opening, so I think that was OK. Non-Consecutive Numeral needed a little trial and error too.
IB puzzles were VERY VERY EASY :D, we made it in a hurry, so you're right on that aspect. (Maybe thats why you earlier commented that 10 sudokus in 2hrs shouldn't be a problem ;-) )
