Advice for student - Summer classes?

Hi ER nurses! I’m a BSN student in an accelerated program, graduating in December. My dream is to work in our level 1 trauma ER someday. I’m waiting to hear if I’ll get an externship at my dream hospital this Summer, but I also have the opportunity to take a couple of elective classes this Summer, and I’d love advice on how useful they would be for ER! One is on trauma-informed care (childhood trauma, not blood on the ceiling trauma) , and the other is EKG interpretation. I want to take both, but if the Summer load ends up being too much I may need to drop one. Which do you think would make me more attractive as a new graduate applying to the ER residency? 
 

My school isn’t offering the critical care elective (sob), so that’s not an option. I am working on getting my ACLS and I’m gonna try to take the Society of Trauma Nurses TCRN prep course before I graduate too (yes I’m extra but we are getting NO clinical experience because of COVID so I figure I may as well get all the book learnin’ I can ??‍♀️).
