In practice material Scattered Sudoku. After entering 5 at R2C5, 2 at R8C9 , non of the colored cells can contain 2?
hie
i think entering 5 at r2c5 itself is a wrong step , in that row 5 can be at r2c8 :) |

Does the Sudoku XV in the IB have 2 solutions? I have a different solution and I don't see any mistakes in it.
In your different solution, have you taken into account that there must be a specified number of corresponding digits per row in both grids on the same page?
Ah! No, I had not. I am notoriously bad at reading the full instructions ... even as I wondered what those numbers in the middle were doing there ...

I attempted the chaos renban only after the test...and found it to be easier than some puzzles worth 30-40 points. I know it can vary with individual strengths, but that's a hell of a lot of variation! |

I know it can vary with individual strengths, but that's a hell of a lot of variation! I agree. The chaos renban took me 10 minutes, while the other 100 pointer, x is alive took me 20. There's a few others that I think are incorrectly valued too, but the chaos renban is probably the biggest sore thumb I saw. |

Points distribution is mostly a very hard part of writing a test. I am lucky to have a small team of testers, who are all well experienced sudoku solvers. There is quite some variation between their timings, so I understand the responses here. Especially the Chaos Renban puzzle has a shortcut that makes it easier solvable; the 5's play a crucial role in all five renban groups. Noticing that makes the solving process a lot faster.
It is always worth looking to high pointers in a test, even if you are not among top solvers. It might be better to look at puzzles that you are good at, no matter how much points they are worth. |

This time unfriendly contest for players without printers.
These tests are always made to be printed. Puzzling is in general a paper and pencil activity (although I admit some of that is changing). So being without a printer will always make it a bit harder to solve. I don't exactly see what makes it unfriendly though. It might take a little bit more time writing in paint, but I don't see how that can be changed fairly. I for example aren't very skillful in online applets, so that would not give me any advantage if those were made. But I generally feel that some people get a distinct advantage of solving in an online applet as they employ a solving style that would be very impractical on paper.
I personally don't have a properly functioning printer right now. So I did it without a printer in paint. I thought it went pretty well. I would have probably done better with one as it's much easier to write and keep notes and write quickly on paper than in paint. But the grids were easily copy-pasted into paint two at a time because of the layout, so it saved some time in having to copy paste all grids separately. I could solve 2 puzzles and then put in the answer keys 2 at a time, saving me some time in having to switch windows a lot. I did last week's test in paint as well and I thought this one was much friendlier in having to solve in paint.

The only complaint is that there wasn't online solving. It is unconvience for people without printer. |

A bit too much math types/sum restrictions.
