Last year the threshold was 104 and this year people seem to have found it a bit harder, so I would say it's possible that a score of 99 might qualify.

I accidentally did 2017 digits rip, think I got 115 in the end, didnt read scalene on Q4 wbu

Unlike you I did read all the questions properly, although I still couldn't figure out Questions 19 and 21. If anyone could explain them, I would be most grateful.

Sure, 19, i am sure you know the triangle inequality, it was just this but for 4 shapes, so 1,2,3,6,11 was the 'best' case scenario, 11 -->D
21) Ill send a copy of my diagram in a minute

I got B for 8, not D, and I didn't answer 21. How did you go about doing it?

8B is correct. You can just draw the diagram and count that there are 84 squares.
21 I couldn't do.

Are these all correct if so is 109 enough for BMO qualifier?
