<p>That’s your decision. At minimum you need 12 credits a semester to count as a full time student (3-4 classes). I usually do 18-22 credits (4-6). Since you’re not charged by credit, mind as mine the most from your tuition.</p>
<p>You can go into “business,” broadly defined, from any major. That includes AEM, Econ, or Chinese Language and Literature. </p>
<p>If you wanted to take courses more obviously germane to business, like marketing, accounting, and finance, then AEM is likely a better fit. If you wanted to take courses related to the economy and public policy, and are comfortable with integrating more mathematics (eg calculus) and statistics into your material, than choose Econ. </p>
<p>Also, you may consider double majoring. Econ majors often double-major in government or math. Even if you don’t double major in Arts, you can still take business-related courses at AEM and other departments. </p>
<p>Another thing to consider are distribution requirements across schools. For example, Arts has a language requirement, and (I think) more required distribution courses.</p>
