One of the things about the Oxbridge system is that tutorials are compulsory. They're traditionally the primary channel for teaching: you might go to a lecture to hear some interesting things, but the real work is the reading and writing you do in preparation for the tutorial, so you'd better go to them. The standard tutorial is one fellow and two students, so (unless your tutor is hopeless and your tutorial partner is a narcissist), you will get the attention you need. Even if you have a tutorial where there are four of you (where the tutor is a rare specialist who has a lot of students to get through!), if you get stuck listening, at least you're hearing the same information that the more vocal students are!
