Xana, I think I can help you there.
I attended Vancouver open day, and all of us who passed first assessment had to write the written exam.
Some native English speakers like real Canadians failed the exam as well.
I think the level of difficulty varies from country to country.
There are couple passages to read and you have to answer some questions to answer.
Then there are matching type questions for some vocabulary from the passages.
Also there are number of questions where you have to read what the sign says and paraphrase them.
They are all multiple choice and they are not difficult but extremely confusing.
Then you have to write a short 'essay' but really just something like a paragraph is fine.
I guess the content doesn't matter as much as the writing style because I wrote complete bull**** and still passed.
