It's not that bad if the test is put together well. I much prefer doing the full experiment. I think the reason they do it is so that they can test us on certain parts of the scientific method, and really figure out what we know and don't know. It's normally easier to....Woah..Experimental Design...IN STATIONS? That's smart, and a bit dumb at the same time...But a good challange! Though I wouldn't want to do Exp Design in stations, but I'd like to see others do it XD
Just thought of another story. My first year at regionals one of the stations on the Experimental Design test didn't really relate to Exp Des. Luckily it related to Road Scholars, which one of my partners had, so we were all good.
