First of all I wanna say that we all are with you and will pray for you....
Dear knok,you were very helpfull to everyone in this forum, and I am sure your kindness will be paid off.
My tips
1.BELIVE IN GOD whatever happens(even if you fail 1000000000times)
2.Be natural,don't think that it is an exam,think that you are in real situation.
3.Don't even think that it's a last chance to succeed,there is always another way out of the situation.
4.Practice everyday,espacially opinion questions.Pay attention on grammar and your voice.Record your answers and after listening them correct and rerecord.
5.Listen to ESL podcast(eslpod.com).I found it very usefull and even after passing the test I keep listening to it.
Be confident and never give up.:tup:
I hope everyone will pass.
GOOD LUCK AND GOD BLESS.
