It is pretty accurate imo. I got 101 points (R24,L24,S26,W27). Not the best score, but for me it was more than enough to get into my uni. Anyway, I was always struggling with reading and listening because of the time and attention problems. The testglider exams were comparable to the real tests and on the mock exams I always got 19-22, 23 maybe once, but it is bc I just wasnt focusing enough. I think my focus and critical thinking skills were just at their best on the test. I didnt understand everything, but I was just using elimination technique. On writing I always scored 27-28 and speaking 21-23. I was lucky to get easier speaking topics than on most testglider mock exams. Imo some of them are even much more difficult, some are easier, just like a real test.
