  47. TYSM! I was only stuck on the first one and thought that it was another one. Since there are only 4 questions I would have gotten a 75% and I currently have a B in science. Normally for me that would be fine but my mom is 100% stuck on the idea that I will be a new Albert Einstien when I grow up :( She gets really angry at me when I even get B's!
