ar3 Considering you want to go into law, I'd say that modern history would be a very good choice, as the style of learning is most similar to that of a law degree. And considering you're interested in law you must be strong on the humanities side of things so I'd say that if you are modern history is a wise choice. In terms of choosing between biology and psychology, I'd say it's personal preference, both are sciences. My friend, who's planning to study law switched out of psychology and moved to biology. However, you might like psychology. I'd suggest doing some research into the topics covered in the syllabus of both subjects, and choosing based off of what interests you more. Both bio and psych are good subjects. Hope this helps.
