When is a good time to play rank?

I have been playing this game for about a month in a half now and pretty much play at least 3 to 4 games a day, more on the weekends. I'm still trying to learn some technical and strategic things. I would like to know when would be a good time to start rank? The problem I have currently is consistency. I feel really comfortable with 3 champs at top/sup/adc, I need to jungle and mid more. Any recommendations on this? I'm level 39 btw if that even matters, Thanks!
