Drain or Drown?

I have a biology test tomorrow on genetics which I am going to flunk, not because it’s difficult because it isn’t, it’s probably the easiest chapter in biology and also the most interesting but my problem is that I can’t focus on what I’m doing. I always start thinking about other stuff. So, is it better to try and drain your thoughts or just drown them and force yourself to focus?
