I have ALWAYS got straight 1s for french, throughout 3rd and 4th year. Today was a total letdown, and I actually had to MAKE up most of the answers. I am sooooo dissapointed about the listening! I came home, and cried :| reading was actually ok, so I hope that bumps the grade up a bit, but listening = nooooooo! I could hardly even make the CD out, as our volume was booming! I'm so going to complain to that stupid SQA if I fail that. Even our teacher found it hard, so what does that say for us 4th years? I really don't know :( these exams have all been rotten, and just can't wait till the summer ;)
