The real test was grammatically correct. But the questions and the choices (multiple choice format) - I think there was something wrong there. I was pretty sure I aced the Listening part. I understood everything perfectly. But according to the test results, I had a few mistakes. The Reading part - that was very problematic. There were times when I wasn't sure if the answers were really there. Or what was really being asked. Very vague. Well, the website had a few grammatical errors, anyway - First sign that this test shouldn't be trusted.
