Помогите!!!!!!!!!!!!!!!!

One of my favourite subjects is Sociology. Actually it's my class's favourite subject because we dont usually have exams and H/W, and even if we do, we do it oraly.I'm one of the best students in the class.
The next subject I'll tell you about is Saving Lives(Это ОБЖ, если что.) 
All of my classmates like it by the same reasons, as the Sociology: rare H/W and exams and a nice teacher with good sence of humor.I'm good at it, as well.
