I'm not sure if this is a joke or not, but I'll try to give some serious advice in the off-chance that you're being serious.
Firstly, i think it's hard to determine before actually going to college and taking political science classes that you'll enjoy it. I studied PS, and I enjoyed it but I could never have known. I also studied philosophy, and I enjoyed SOME of it, but a lot of it I found very frustrating. Although, I must say, I believe philosophy was far better of the two disciplines in terms of helping me develop my "thinking" skills and teaching me how to write.
Secondly, counselors at colleges are worthless. I think you'll find all the information you'll need by surfing these boards and filtering through the junk. There's some great advice on here, and a lot of counselors don't really understand what law school admissions are like.
Thirdly, there's no reason why even if you tell your counselor that you're going to law school that your class schedule will change. Pre-law is not a major, and if there's anything at your school which gives a designation of "pre-law," I'd avoid it like the plague. With that being said, if your goal is going to law school, that may change YOUR preferences as to which classes you'll want to take. You'll probably take Constitutional law since you'd probably be more interested in it. If your school has such distinctions (mine did), you may take political science classes which are tailored towards "legal" questions. But since there's no required curriculum to enter law school, there is no formal change a counselor would require of you just because you are "pre-law."
You may then be wondering: "what types of classes should I take, etc.?" The general rule of thumb is take anything that you enjoy and will get high grades in. Law schools care about GPA and LSAT. If you rock those two numbers, you'll rock your admissions cycle.
