2 types of IELTS --- Academic and General
I took the General since I want to qualify to work in UK, AU, or Canada.
THINGS to REMEMBER:
> Practice reading and understand what you're reading.
> In Speaking part, just remember PRACTICE MAKES PERFECT.
Record your voice while answering sample questions the interviewer might ask. Review them and know your problem areas and improve them. Also remember there are no right or wrong answers in the Speaking. Even if the interviewer asks you something you haven't experienced but you have read about it just expound on it and build the topic from there. This is the crucial part so no, uhms... aahs... while speaking to the interviewer. Stretch out your asked topic a bit and don't stop talking when you haven't seen the interviewer satisfied.
Hope this will help...
Good luck!
