Investment Banking Workshop Indiana University

I am a high school senior seeking to join the Investment Banking Workshop at the Kelley School of Business at Indiana University next year. Can anyone in the program, alumni of the program or anyone who knows about the program in general tell me about what I can do now and during freshman year to help bolster my resume/application for acceptance into the program? Which clubs are best to be in, useful electives, books, outside study material or information, who to network with and how to network, or any basic tips will help, thanks.
