There's a few way you can approach this.

For starters, here is a breakdown of LSAT scores by fields of study:

If you're not too keen on reading, here's a brief summary, with average score:

1) Math/Physics 160
2) Economics/Philosophy/Theology 157.4
3) International Relations 156.5

...

27) Pre-law 148.3
28) Criminal justice 146


Speaking purely from personal knowledge, I would say that, knowing what I know now, I would have chosen Philosophy and Sociology to prepare for a legal career. Both of these fields will provide the theoretical background necessary (recommended?) for the practice of law. In addition, philosophy's emphasis on straight-up reading comprehension is a major assistance to building a very important skill for practising law.

Depending on your current institution, or the type of law you would like to practice, I'm willing to bet that there are other departments that would be interesting/useful as well. For example, many IR/Poli Sci departments will offer courses that deals with international law, though likely indirectly.

I have recently accepted my offer to Ryerson's Bachelor of Journalism program. I was wondering if I would be able to pursue a career in environmental law after completing this undergraduate degree? I have already taken a look at the electives that are available during this four year program, and I know that environment-related courses are available. However, will these courses and this degree make me eligible for a post-graduate degree in environmenal law? Will my knowledge be sufficient enough? If not, what types of law can I pursue with a Journalism degree? Please let me know soon! I need as much advice as I can get.
