Oooh, it is difficult for me to pass the IELTS.

I graduated from my college last year and on Sep 1st, 2012, I started preparing for IELTS. In the beginning, I thought I would pass the exam very easily. Unfortunately, i changed my opinion at once after doing some practice. Reading, listening, writing and speaking, I found it was difficult for me to get a decent score on any part (including reading, listening, writing or speaking). Will someone help me?

Let's look at this sentence: "Reading, listening, writing and speaking, I found it was difficult for me to get a decent score on any part" - 
In English the verb has to follow the subject:
subject -->verb-->object
I-------->found-->it was diffiucult.....

You're grammar is really good. I think you just need more practice. Doing more reading can also help with writing.

No, it is not difficult to pass. Practise daily, bit by bit. Note your difficult areas and give them more emphasis.
