I will have to go here. And it's a T4. I have two children and I don't want to move them.
Go check out lawschoolnumbers.com for the law school in your area and see what kind of numbers it takes candidates to get a good scholarship there.
If you do well in undergrad and get a good score on the LSAT, you might be able to go to a T4 for next to nothing.
Of course, there is no guarantee that you will be able to keep the scholarship for all three years, so you'd have to look into that when time gets closer.
Also, take a look at this chart
http://libarts.wsu.edu/philo/overview/grad-admissions.aspIt tells you the performance on graduate admissions tests by major. I think it has more to do with the type of people that choose the majors than the majors themselves, but it's still interesting.
My biggest warning against going to law school is that it's unpredictable. The debt sucks and the job market sucks worse, but a hard working graduate can make it through. But I never seem to talk to anyone that ended up practicing the type of law they set out to practice. So how can you possibly decide if it's what you want to do? When you go to law school you are totally rolling the dice. It's hard to predict how well you'll do, it's hard to predict whether you'll like law school at all, it's nearly impossible to predict what type of job you'll get (at that point), and it's hard to predict whether you'll like the job you do get.
That may be true of many professions, but hopefully those professions have better job prospects and a more surely defined career path.
For example, many people would never want to be a pharmacist because it looks boring and you are basically a glorified cashier. But, you get paid $50+ per hour to be a bored and glorified cashier, and you have a good idea of what it's going to be like going in.
