What's your rank, and (maybe) why are you there?

Silver 3. Got it yesterday, promoted from Silver 2.
I just started playing the game, and according to some experts in the field, one's real ranking shows after about 500 matches. Not sure how true is that.

But I'm here 100% because of my aim. I'm still experimenting with the mouse sensitivity, but it's definitely gonna take more time to have a decent tracking and learn to aim for headshots more.
