How could I explain a 2 year gap in obtaining a degree due to dropping out and then returning?
I've been doing my engineering degree since 2007. I did very poorly on my first year and it wasn't a really good time in my life, so I took a break and returned in 2009. It took me until 2011 to finish my first year. Currently, I'm in my 3rd 2nd semester. In my resume, I list I started enrollment in 2007. My transcript states this too.
Should I add an explanation in my cover letter for my delay, or should I only bring it up if they ask?
