ELI5 - The 'Ranking up medal

So i’ve only been playing Forza 6 since Christmas when I bought my son the xbone as his present.

So far i’ve mostly been doing career to get myself familiar and to build up some credits.

In the past month i’ve been delving more and more into the online multiplayer aspect. Last night when I was finishing up the “Ranking Up” badge came up and it mentioned something about division 1.

Can anyone explain what this means as any google searching has only confused me further. Is there a ranking system I wasn’t aware of in just the general online lobbies? Does it have any impact on your online play?

I’m not sure what your achivment means but this is how things work online. you have your driver level which increases over time depending on how much xp u earn from racing online and in career mode. In the back ground you have your trueskill. This is based on win loose ratio and who u beat giving u more points for beating ppl with a higher trueskill. Your trueskill is supposed to determine who u get put in a lobby with but this is overwritten when ppl join on there friends. Finally you have the leagues. Your league is determined by your truskill if u havnt already participated. If you have then it’s based on your league performance. In leagues u can only play with ppl in the same league and its a much better way to find a good player match.
