I'm currently looking for a new job and found a very interesting job posting that is in the exact field I want to work in (software development in medicine). I specialised in university in that field and took several courses where I got excellent grades. However in the past two years I worked in a completely different industry and haven't really been in touch with it.
Would it be appropriate to list either these courses in my résumé and/or specifically mention them in the cover letter? At the very last the the hiring managers would see it on my Bachelor's certificate anyway. Or are past activities or courses in university not relevant after a couple years of working experience?
