Muhdzailan,
I will suggest that you try improve your spoken and written English with or without sitting for the exam again, this is especially important when it comes to interview. If you can speak well enough to convince them that your grade doesn't matter, they will let you go for written test with your poly diploma.
So, some preparations are definitely recommended...
