Hi emad,
yes, you are right. English is not my first language and I had to take the IELTS, twice. The first one I failed in the writing component, so I practiced it a lot for the second try.
When I applied to take that exam, I also bought the book "How to prepare for IELTS" - British Counsil. It is quite thin acctually, and I totally recommend it. You may also find some free online exercise samples.
It is possible!!!
