While doing this exercise, it went right on to the next section without giving me the chance to compare my answer or give myself a score on two of the sections. Hence the score of 50 out of 60. No big deal, since this was a very simple lesson for me. (Although it was useful in learning and recognizing the names of brands of beer, even though I don't drink beer!) I just want to do all of the listening exercises for practice. 

I simply wonder what might have happened.?
