watch english tv shows, read newspapers and novels, as many as you can get your hands on, and never be afraid to converse in english,

During my school years, my english was pretty good because I always playing PC games. I like to mimic those voices and an English dictionary was always by my side when playing them.

take any engish short courses....my sister took it before entering matrix...the course is more to public speaking

like what my English teacher used to say, though it sounds stupid, reading fairytales story books do help. because they use simple English. Read it more than once. You'll naturally catch the grammer and all. Then you can go on to newspaper all and blahblahblah VOILA!

of course, speaking if more regularly, helps too. and i do agree that, if you used to talk to your friends in Mandarin, it's a bit tad weird to speak English out of a sudden. Ask them to help, for you want to improve ;p

And don't be afraid to make mistakes, because we learn from mistakes.

not really...some are affordable-worth the money
one that i suggest is this english course put up by UTAR (the one at PJ)
something on improving your proficiency in English....saw that in the newspaper advertisement    ...for 12 weeks, got elementary, intermediate and advanced level....so need to take test...then they put you at the level u need 2 improve...

u can try lar..call the UTAR and check 

i agree. This forum definitely suck balls when it comes to English. My English is deteriorating ever since i visited this forum "frequently".
