Hi! 
I was just wondering: are the JLPT levels a good measure of how well you'll do in VCE? If so, what would each level more or less translate to as a study score? And what would be a good level to reach before taking the 3/4 exam?
And if they're not, why is that?
Hi Hiea
VCE Japanese has writing and speaking components which the JLPT doesn't, so it probably won't be the most accurate indicator of your VCE study score. JLPT has reading comprehension, listening and kanji/grammar components and all answers are multiple choice. I think its main advantage would be that you can improve your skills in those sections for VCE, but you'll still need to do other preparation for writing and speaking.
I think students who get a 40+ study score would be able to pass JLPT N4 (I think N4 is slightly beyond the VCE course however). Although, as kanji/listening/reading is the focus of JLPT, people lower and higher that the 40 mark could pass or fail. It's still good practice nonetheless, especially for listening and vocab building, if you're motivated enough, get stuck into the N4 practice problems.
