"忙到一张脸痘痘都长不过来了(它都默默长到耳朵上了。。。囧)。。" haha, really? never know pimple can grow on ears.
to be honest, I think study in oz is very relaxing unless u want high D, try to get higher marks from assignments and get pass on exam, then you wont fail in the end.
try your best to practive speaking first, drop the writing aside as long as you can pass exams, so you can have good impression on interview for any jobs that you are looking for. that's my personal experience. stay working for aisan owners will never get you in to the country. good luck!
