About 10 people left our room after the hour (class of about 30-ish). Only 4 people were left in the room when the exam ended. I would never leave an exam, I would at least just sit there and read over my work. Not that I have experienced that yet, I'm always pressed for time.
I thought it was great. Multiple choice were easy, short answer were reasonable, definately better than the trial. I liked the second extended reponse, I just didn't like the Nutrition question about the Physical/Economic effects.
My reasoning behind picking D was.. A and C definately out. Then genetic engineering I don't even remember learning about in Food Technology, I knew it from Biology or something.. so D.
No idea if it's correct.
