I would suggest that for getting into law you have chosen appropriate subjects. I don't recall hearing about any prerequisites bar English, are there any? (make sure you are doing them)
At this point in time I'm sure you feel you are overloaded with holiday homework, but in reality you probably aren't to the extend you think you are.
Think about it like this; you have ~ 7 weeks 'til week 1 of term of next year. Some school terms are only slightly longer than this so you have plenty of time!
From what I have heard psychology is a rote learning subject and requires quite a deal of study to do well. Have a read through
A General Guide For Psychology. and
Psychology ResourcesBusiness management can be performed well in once you have a good grasp of the definitions and know how to interplay them together, you should put a great deal of effort into practicing particular questions as marks can be easily lost on the Exam when they are worth 10 marks 6 marks etc. I certainly believe you should use Shinny's notes for BM:

As for legal studies, I know nothing about it but have a read through the stickied threads in the LS section:
Legal StudiesTo perform well in year 12 you need to keep motivated and remain physically and mentally healthy, whilst being relaxed. This may involve doing exercise, having a good sleeping patter (people suggest not going to bed after 12am) and maintaining sociable behaviour. Also, make sure you have a bit of fun, for many year 12 is the most enjoyable year of their lives so make it a good one. It's not the be all end all of your life if you don't perform as well as you like, just try your best and take everything as it comes.
Finally, which maths? Futher, Methods, Specialist?
