I used to teach a class for 3rd & 4th year students in which this specific question came up all the time.
The key factors in this question (and my answer) are:
- you are a student in a major and and are taking courses along a particular path
- you have little to show in traditional resume form, mostly because you're a student
- you are not applying for a full-time position somewhere, but...
- you are applying for a summer internship in which it is likely very much assumed that you are a student
In this situation, it would be completely reasonable to frame your academic work in these terms:
- something, at some school, expected SOMEYEAR
Completed Coursework in Major Field
something really specific beyond intro, completed SOMESEMESTER
something else really specific beyond intro, completed SOMESEMESTER
Upcoming Coursework in Major Field
- something really specific beyond intro, to be completed SOMESEMESTER
Note that I wouldn't list upcoming coursework beyond the next semester.
What this structure allows you to do is to point out in your cover letter exactly what has & will be preparing you, as a student, for the summer internship to which you are applying.
Taking off the teacher hat and putting on the hiring manager hat, this path of learning/connection to what you'd be using this knowledge for in an internship with me, is exactly what I would want your resume and cover letter to convey.
