In this picture we see a group of teenagers doing lessons together. From their faces, you can see that they are fun and not bored. There's a boy in this group. He's sitting at his laptop and typing a lecture. Next to the guy sits a girl in green. she also writes something, but it's a lecture. everyone else, too, busy and writing lectures, sitting in the library.
