I didn't fail the test, I definitely passed. But I wanted to get 80-90%, and now I think I'll be with all the other average scores, or around 70% if I'm good at guessing (50% is the minimum passing grade). Most people just barely pass (well most people fail, but of the people that actually studied for it) and I don't want to be in that group.
Especially if they care about those individual scores when I'm applying for university, saying "I was hungry" sounds like a sad excuse for a poor listening score when I have already gone to Japanese university lectures and followed them just fine. I'm generally a horrible listener in any language when it comes to remembering lists of directions and the like though. But I feel reading comprehension is piss easy when everyone else thinks it's the toughest section so there's that.
