I’m an IELTS geek and I know the test very well. There are other courses that have been put together by people who aren’t even teachers, and who certainly have never been examiners.
Very often these courses just abandon you as soon as you have paid, and so you lose motivation.
I think it’s my job to keep you motivated, keep you studying, encourage you to carry on when the going gets tough, and be there to help you when you need support.
Oh yes and I forgot to mention, my students get excellent results! I’m very close to them and very proud of what they achieve.
