In the picture I can see three students taking an exam. The girl in the middle takes a sneak peek at the sheet of the person sitting next to her. It looks like she's cheating.
1) I think the girl is stressed out. She's probably worried about getting a bad grade, or getting caught cheating.
2) Being honest in exams is important to me, because they're a way to measure our knowledge and progress.
3) One day my friend's teacher caught her cheating on a test, and exposed her in front of the whole class, which was embarrassing.
