- How to revise for Legal? (i.e. would that just involve knowing the textbook "inside and out"?)
I basically took the study guide and broke it into the outcomes, using them as headings and writing notes on each part. Worked for me. Knowing the textbook helps, but applying it is better. Considering the outline will change next year, it'll be different for you: apparently it's more about applying than the knowledge of the textbook, etc.
- Is it hard to do well in Legal? (i.e. get over 40 raw?)
I wouldn't know. Don't get my results until December 13th (my 18th birthday, coincidently). If you get above 90% now, you should do well next year. It is just about expanding on the knowledge you learnt this year.
- Needing a tutor for Legal?
No, just make notes on what you learn every week, so you can summarise them at the end of year exam. Tutors can help, but they might be really limited. I'm not sure - never used a tutor.
