Should graduating high school students know personal finance?

<p>I have to choose a practical elective for my senior year. There is one called Personal Finance, which deals with how to manage a checking account and banking/insurance etc..
I'm thinking since I don't know jack about finance, I should take it. </p>

<p>However, there is another class called Exploratory Business, which deals with managing your own business, stock, and investments. Since I'm thinking that I want to go in business, I want to take that as well.</p>

<p>I can only pick one because of schedule restraints. What do you think I should take? Any comments would be appreciated.</p>
