<p>I hope this link helps to answer some of your questions. I think instead of getting two BA’s or BS’s you could just receive one BA or one BS.</p>
<p>It’s very possible to graduate in four years. Especially if you can do a lot of double counting between majors. I don’t think you will get charged extra for graduating in four years. If you wanted to graduate before four years, then I think you would, so you should be good.</p>
