High school 11-12 )

Hello there i have just started going to eleven and twelve and i have to say it's really easy than the other classes in the past and it actually feels like special needs schooling and it just feels dumb ) Ok what i'm trying to say here is that choosing level two for my studies was a big mistake there is three levels 1,2,3 . And most of my people in those classes are special needs and i'm like eeerr i feel not okay around them because they kind of shout randomly . I feel stupid when i go into the classes because of you know whom . I try not to judge but it's just eer . Has anybody else been in a situation like this ?
