You are in luck.
My daughter, who is a quite successful patent attorney, answered all your questions within 30 minutes. You must have interested her greatly.
Here are her answers: (free advice from a very successful patent attorney for the last 5 years)
GETTING INTO LAW SCHOOL
What courses/major should I take in college? Anything you want. Makes no difference whatsoever once you get to law school, so take whatever interests you. The only exception is if you want to be a patent lawyer (i.e., someone who prosecutes patent applications at the USPTO), you have to have a degree in science or engineering.
Is there any disadvantage if I'm not a pre-law major? No, see above. In fact, many schools don’t even have a pre-law major.
What's the best way to study for the LSAT? Best way is to take a review course, but they are expensive. Most of them, including Kaplan, put out books you can buy much cheaper for independent study. That’s how I prepared.
Do I need any math skills? Nope. Lawyers are notoriously bad at math.
Which law school should I go to? Depends on lots of things. Pedigree is important if you want to work at a big law firm, so going to a good school can be important, but also extremely expensive. Many state schools are more reasonably priced and still well thought of (like University of Texas, University of Michigan). My advice would be to apply for scholarships everywhere and visit as many schools as you can to try to see which is the best fit.
If I want to practice in a certain state, do I need to go to a law school in that state? No. It is definitely easier for students from in-state schools to find jobs at local law firms as a practical matter, but especially big law firms are looking to hire students based on their grades and experience, and the fact that you are from out of state might even be a plus because it creates diversity.
Can I still get into law school if I have a mediocre GPA/LSAT score? Yes, just not as good a law school. Better the GPA/LSAT, better the law school.
What's the difference between a top-rated law school and one that's not so highly rated? There are a lot of factors that go into the rankings. Number of tenured professors, student-to-teacher-ratio, volumes in the library, etc.
I'm in high school right now.
Is there anything I should be doing to prepare myself for law school? Read a lot.
What's law school really like? It’s actually a lot like high school because you tend to have smaller classes with the same students (as opposed to college, where you may be part of a sea of faces). It’s generally a pretty competitive atmosphere, but it’s also where you’ll make some of your greatest friends.
I've heard law students are really competitive. Is that true? Yes, definitely.
I've heard that law professors are real jerks. Is that true? Not at all. There are jerk law professors just like there are jerks anywhere else in the world, but I personally only had a few professors who I would consider jerks.
Is the practice of law like what I see on tv? No.
How much do lawyers earn? It varies considerably. At the low end of the spectrum are lawyers who work for the government or for non-profit organizations. They make as little as $50K per year. On the high end of the spectrum are lawyers in private practice who are partners at multinational law firms. They make as much as several million per year.
How many hours a week do lawyers work? It varies considerably. Lawyers in private practice at big law firms typically work 60-80 hours per week.
I want to make a lot of money. What area of law should I go into? If you are entrepreneurial, then the most money to be made is doing contingent-fee work for plaintiffs. But you have to win significant money for your client before you’re going to get rich doing that, and it involves a lot of risk (i.e., if you lose, you’ve spent your own money on the case and made nothing). The more traditional way to make “a lot of money” practicing law is to work at a big private law firm. Associates start at around $160K out of law school, and it goes up each year from there (to around $250-300K by the time you are up for partner). To do so, you need to either go to a top school and do reasonably well or go to a mediocre school and do very well (or know someone).
Are there any areas of law that are "hot" right now? Intellectual property.
I want to be a lawyer but I don't think I'd want to get involved in trial work. Is that possible? Yes. That means you want to be a transactional lawyer. Transactional lawyers work on deals. They do not go to court – ever.
Will I be able to get a job once I graduate from law school? Is there a "glut" of lawyers right now? Yes there is a glut of lawyers. If you do very well in law school, you will be fine, but I would not want to graduate in the middle of my class from law school right now. It could be difficult to find a job, as the market is quite saturated.
