I am a busy professional so wanted to get the most of my 2 hour/night study sessions. Your interface is spectacular. I don’t have to flip pages to see answers or need a stopwatch with me to assess my time. The amount of practice sets provided is enormous. Also, the answers and description from the instructor about why this should be an answer helped me understand the issues I had. I think your course was an essential factor in getting a good score in the IELTS and I would recommend it to all.
