I'm also studying for my Torts final tomorrow and am doing pretty much the same thing (minus the study group, which isn't my bag). I don't find it quite so important to actually take the practice exams, as far as writing it out, as long as you are able to spot the issues. If it's open book/notes/etc, I recommend making some cheat sheets by topic (Business, Children, Employer/Employee, Medical, Guest of Premises, etc). I feel like a lot of Torts issues connect to a certain kind of situation, and so if I can identify the situation topic (like, say, an accident on someone else's property), I can run down my sheet and make sure I'm hitting all the relevant topics that usually come up in that situation. Might not work for you, but I thought I'd mention it.
