I think its important, just as in English, to learn to correct yourself; a regular tutor shouldn't be necessary in a subject like this. If you have questions, post them on VN or ask your teacher. Besides the monetary cost, a tutor could end up being a waste of time as you'll be sitting there thinking "I could have understood this in one read."
Perhaps that's just me because I'm OK with understanding commerce and humanities subjects' theories, but I can't see it having the same benefit as a science tutor. My approach to Legal and Psych will be like mine to BM, learn to mark myself so that in the exam, I can edit my responses where necessary.
Alternatively we can, later on in the year, make a 'Mark my Response' thread like we did in BM for the 10 marker. You post your response to a question, everyone marks it and gives criticism.
You're a smart guy EPL, I think you're putting pressure on Legal so much you feel a tutor is necessary, when in actual fact if you relax and look at the concepts they will click.
Hope that helps.
