Lib Arts Major

Hey everyone. I'm a lib arts major from a top 10 liberal arts college hoping to break into i-banking. I am a Political Science and Spanish double major that has taken Intro to Accounting (woohoo) and aced the course. I am definitely late to the game as I am already a senior, and have only had legal internships and received grant stipends for political science related research. Luckily, many students from my college go into banking and consulting (including those that are not econ majors). I would love any tips about outside courses to pursue to gain technical skills, and how I can better my changes at earning an internship or job. Would enjoy hearing from others that are or have been in my same position.
