I'm the best !!
lectures r where u'll have heaps of students sitting n one lecturer standing in front n talking..... 
tutes r basicallly much smaller than lectures n u can interact easily, ask questions, answer questions.....most of my units last yr , we used to have hw which used to be checked in the tutes, answers were discussed, there were some group assignments in tutes n some fun 2....
another difference , the tutor will know u by name , not the lecturer
n its much easier to make friends in tutes, in lectures i prefer sitting by myself!
