It can arguably be considered fraud and probably is false advertising, but what are your damages here? Not really something worth suing over. You might be able to get a partial refund from the teacher.
One would have to see the flyer and website to know for sure.
If 8 simulated exams were available, and student had option of taking all 8, then no fraud, no false advertising, no criminal act and no civil liability.
If the student never even saw the flyer, then it is irrelevant to that student's claim. The student did not rely on it in deciding to sign up.
