I think the others got the patent/regular bar distinction covered. As far as question No. 4 goes... I wish that someone would have shown me what an office memo, a trial brief, and an appellate brief look like. I wish someone would have taken me through the steps of "Here's your fact pattern and legal issue, now go out and give me an office memo." That would have been greeeaaat! But no, I had to learn the hard way-- my writing class.
