You will do all right on the verbal sections if you haven’t forgotten how to pick up a book or a newspaper. The math is where most people trip up. I have not taken an SAT since high school, back when it was done in cuneiform, but I did have to take the Illinois Basic Skills test for teachers, which is very similar in form and content. There is a verbal section, a math section, and a writing exam. I did fine on the math, but I’m an engineer and I work with it daily. When people have to repeat the IBS test, it’s almost invariably because of the math, and all of the prep courses you can sign up for emphasize it. Don’t worry about being in college as an older student. There are lots of people who do that. The young people will want to know you, and they will not look down on you in any way. What you major in depends on what your goal is. If you mean to improve your employment prospects, a liberal arts degree will probably be less helpful to you than something more focused, e.g., in technology or business, but it will open more doors than you think.
