I am considering mentioning the completion of a JP Morgan IB course on my CV for Spring Week (IB) applications after relevant in person work experience, another activity for the experience section (hoping to have 3 experiences in total, lmk if this is too much). I've heard people online recommending this and others saying somebody shouldn't do this as it's essentially wasted space according to them, so is this a good idea or not to gain offers? At the very least, if it is not suitable for a CV, is it suitable for a cover letter when applying to JP Morgan since it is a JP Morgan specific course?
