Вот-так вот:
I’d prefer to stay in the biology class. Biology class is really interesting to me because there are a lot of skeletons and some photos of the animals. It always makes me curious and interested in it . But I couldn’t observe it for a long time because I i was looking at these thing too long time and it got me bored. But on the other hand, I reached some knowledge . I think that was really interesting but this job is good for the people with good patience.
