my JPSAE also unsuccessful. stupid fuktards call me at 3pm for
interview at 3.30pm...I was at school in Bedok and they ask me to
go over to Clementi by 3.30..wah lao...then they say if u cannot I
will give ur chance to other ppl...
so i say ok, i go now...while waiting for taxi the person call me
again to ask me to do a d&t artefact and bring over, all by
3.30..i was like WTF? u should have told me like 1 week in
advance..so I ended up quarreling with the person on the phone on
how inefficient their system is.. 
dunno appeal will get or not?
