I'm a Japanese, and I think its reading and listening sections are pretty good. Just a minor drawback: some questions begin with 7~10 when it should be 1~6 first then 7~10, and some practice test having fewer questions than the actual IELTS test (ex. There should be 10 questions for each listening task but there were only 6 for one of them). No comment on the writing and speaking sections as I'm not paying for the premium.
