I took a few of the tests today and I didn't fail miserably. I'm going to give my score and impressions on the different tests so if you want to avoid spoilers, I suggest you don't read the rest of this post.

15/15 also. Would have been more fun without the nationalities to help.

57/80. Really disappointed that I missed a few I really shouldn't have (eg : Coppi

).
Concerning the last series of tests that pigoonse posted :
34/50 for the sprinters. I missed a few obvious one. The "ATM" in the title can be a bit confusing since a couple of the sprinters haven't performed in years. Also, how can Spilak make the list and not Boonen, it makes no sense

My advice, don't be afraid to go for punchy riders that can also sprint.
For the cols, I got 12/24 including all those the TDF has ridden at least 40 times. Clearly, the hardest test of the list.
143 out of 150 for the cq one. I guess I spend too much time on cq building fantasy teams

I'm happy I got the one that the most people forget.
For the classics, I scored 8/9 but I just missed the last one because whatever I tried I couldn't get the spelling right.
