As far as the law course - even first year is not all theory, at least in the past.
Although 'skills' are now in separate units, you still do assessments that involve practical work. Eg moots, client letters of advice
First semester is pretty ordinary due to Intro to Law - i found that subject very uninteresting. It's useful for later, but not the most exciting. Law Foundations (although it depends on your teacher) is more interesting, although theory based.
Second year onwards is a lot better as you move on from the purely theory units.
Wixxy - i did/am doing the same degree. First semester of the HR/IR stuff was pretty uninteresting but it does get better. The teachers who have generally taken the units in 2nd and 3rd year and far more engaging as is the work. If you ever have the option to take the IR Strategy class taught by Louise Ingersoll take it - she is an excellent teacher. That said though the subject is pretty interesting irrespective. Meg Smith is another good teacher - in the past she has taught Negotiation, bargaining and advocacy and Remuneration Theory and Practice.
Also, as far as class sizes - if the day classes are packed you can always change to night classes. Sometimes they're smaller, not to mention the fact that people are often late or don't turn up so the class gets even smaller
