I did my "M" there and failed once for merging to 401 highway traffic "too slow" and not taking up my guard position on the left lane (that was stupid on my part because I should had known that guard positions change depending on which lane you are in). I also did not do my homework or paid attention and thought the speed limit was "50" on Sheppard ave W, failed for riding too slow.
I went again and didn't missed a point or made a mistake, passed with flying colors. If you know how to ride and the rules of the road you are guaranteed 100% to pass the "M" easily at Downsview.
