<p>what is the difference between two groups? why group B has more parts than group A? how do you which group you belong to?</p>
<p>I’d like to know this too. I have never drank and I am in group B.
Is it randomized or is it based on your answers to “Survey 1”?</p>
<p>BBRJSue, I’m in group B too. Do we just have to do the survey and wait? It’s kind of irritating to know that I’ll have this to complete on top of my classes when school starts 
And I’m hoping this was random, although I don’t see why they can’t just put everyone on the same schedule?</p>
