Warning about JCS:
I went to JCS's advance class to try out for while completing the end of my Ikoma pre-advanced classes. So yeah, it's possible to switch schools. JCS's reading material was definitely a lot more harder (obviously because one's preadvanced, and the other's advanced) but the students there were really weak! It's ridiculous because a lot of them obviously didn't really understand what they were trying to 'learn'. The classes at JCS were too big, they have crazy ideas about attendence, and the learning style didn't accomodate much speaking. Needless to say I dropped out of the class pretty quickly.
One thing that I did get out of it though was being exposed to more difficult material and looking at that concurently with my JLPT2 self study, it really helped. After doing my JLPT2, I was able to finish reading my 1st novel, 魔性の子, from the 十二国記 series.
[BTW, that's a good book to read for newbies to Japanese novels, because (1) it's got a great plot and (2) the Japanese is relatively easy.]
arcadefire: good luck for your FT class, hope you enjoy it.
Really missing Japanese classes now... It seems I've forgotten how to converse properly after not practising for more than a year! (reading isn't a problem though) T__T Can't wait for my postgraduate studies to be over so I can return to Singapore and resume them.
