I just took the same test twice about "A l'aéroport". The first time I you said I had 7 correct, 1 near-miss and 5 wrong. I do not believe any were wrong. I then took it again.
This time I went through the vocabulary provided by Lawless for L'aéroport. My marks for the second time were 9 correct, one near miss, one unanswered and two incorrect. Absurd! The apparent unanswered one I had answered and correctly. It was the first question. Why on earth your system ignored my correct answer I have no idea but it is very frustrating.
The two apparent wrong answers were not wrong. I used the vocabulary you provided. One said that my use of "bagages enregistré" was wrong and I should have used "bagages en soute"! I used "bagages en soute" in the first quiz and had it marked incorrect!
What on earth is going on?
How can anyone have any confidence in how you mark these quizzes?
I look forward to hearing from you.
