Biggest derp moment. Sy and other people who did CSSA trial.
You know the circle geometry. They were 2 circles overlapping each other with cylic quads within them. one of the questions were to prove another set of points were cyclic. so I got lazy and didn't draw the diagram, so I worked off the booklet. so I drew a circle around the points to help me visualise, coz there were lines everywhere. I drew it the first time, but I had one of the wrong points, tried a second time and not using a rule, u can now imagine the shit on the diagram. and at that point I couldn't even do the question cause I didn't know what the original diagram was.
