Do You Know Which Oven Rack to Use?

I am a terrible baker.  Despite trying to bake more (and thus eating more dessert), I'm really not getting better.  One specific problem I have concerns biscuits.  They are always too done on the bottom and not done enough in the center.  I tried a different pan and lowering the temperature and cooking time.  No dice.  Apparently, my problem was the rack position!  I was always putting them on the second to bottom rack.  Next time, I'll try the center rack thanks to this article.  Read on for everything you ever wanted to know about which rack to use....
