Levi, my husband had to re-take IELTS academic 6 times!!!:shocked:Every single time his results came different, sometimes with a variance of 2 bands and always 1 of the modules marked as 6.5 (this mark is sufficient for the needs of all institutions in Canada). We tough that the reading and listening modules are marked by a machine but, but at the center they told us that it is manually graded by a marker. He appealed after the first time, and it was unsuccessful. We decided it is waste of money. After the 5th attempt, he spoke to the manager of the test center and pointed out the variance in marking for each test. "Miraculously", he passed right after this conversation...I am not sure what is the right conclusion in this situation, but you are right, they are money makers, especially when there is no competition among exam providers where you live...and I live in Calgary, which is pretty big city.
