what should I do with my major?

Little bit of introduction of myself… you can skip this.
Hello, I’m a Korean international student in American high school. I will be a freshman in Texas Tech University this fall! I started my high school in American as a junior last year. I am proud of myself to make it this far in very short period… Texas tech granted me huge… huge scholarship with $15,000 a year, and my mother is very happy about this result.

So, when I got accepted to Texas Tech, I found this major called, Energy Commerce. It was fascinating major that makes me to consider double majoring it with accounting. My future plan is to do both MBA & CPA and at the end… I want to be a business controller.
This is the Energy Commerce description that TTU provides

Should I consider double major? I mean I do have time until my sophomore year… but I guess I’m being too excited. Also, do you think this will increase my opportunity to get accepted to great business school? (for MBA). Please give me your advice and please be kind hhaha.

Thank you so much.
