Passing a test takes hard work
I remember working part-time in a language centre that geared mainly towards IELTS, TOEFL and TOEIC. The ladies at the front would tell the students any old bollox. Didn't matter how low level your English was they'd push you to do a the course.
The first thing I'd do is tell the students how difficult IELTS can be. If you're at a level under pre-intermediate, you will struggle (these students harboured ideas of studying in the UK, etc, so needed at least a 6.5 score). I told them they'd be better off learning general English for a while and then come back. So, I'd get that out of the way and I'd introduce the course. We'd get to the first activity and I would see the students' faces drop. That sudden realisation that this was proper hard work.
No word of a lie I had a student ask me; "Teacher, if I did this test in Cambodia, would it be easier?" to which I replied "Is that a joke?" I could see some of the students eyes light up as they thought I was going to reply 'yes'. Unfortunately for them, I had to break the news that this is a standardised test. It's the same all over the world and the reason it exists is to test your level of English. Faces dropped again. I explained to some of the nurses one time that doing their TOEIC test can be a question of life and death for some poor bugger in hospital. The questions aren't trying to trick you - they're trying to make sure you're listening properly and have a good grasp of English.
I think many people believe studying IETLS, etc, to be a status symbol. I've had students study it thinking it was merely an advanced level of learning English. It's not. It's a test that anyone can take to test their level of English. If you wanna spunk god knows how much money up the wall on doing a 60+ hour course and then an exam, go nuts. But understand the reason for studying English proficiency exams. It's not about learning English - it's about learning how to pass a particular test. Your English has to already be good to get a meaningful score that will help you progress to university abroad, etc.
