during the first series of my exams i thought i was failing because i was just nervous....until on my 4th try ive decided this is something serious already that i thought i must seek help from text books, and reading materials....i bought alot of stuffs but it didn't do anything but lower my score.....i just think the more i did well, meaning the more i prepare my answer the lesser my score becomes....but if i don't prepare for it, i stutter and become speechless!!! so i am at a point right now that i dont care if i pass or fail, i will just do my best to be as natural as possible....i suggest, if you're worried about your accent try to converse with a native american or watch american films....or yet, the news...i will continue to pray for all of us here who needs to overcome this worst exam ever!=)
