Incoming Treasury Analyst (Transaction Banking)

Hey everybody, glad to join the monkey community!! I just landed my first job as a treasury analyst at MUFG under their transaction banking department. I was an econ major so took minimal finance classes. I'm working on my knowledge of financial statements and accounting. I'm also taking the WSO excel course. What do you guys recommend me to work on to be best prepared for my first day on the job? Any input is appreciated, cheers!
