Questions from a transfer student

In the fall, I will be enrolling in my junior year at a lower-Ivy after two years at a lesser known public school.

I'm having trouble figuring out how to structure my resume. I would like to apply for Wall Street internships for the summer between my Junior and Senior year.

I'm planning on getting a head start by applying early for next summer. However, as of now, I do not have grades for my new school (I haven't started yet and I will not have grades until after I apply).

For my old school, I have a 3.9+ but will HR departments understand if there is no GPA next to my transfer college?

Also, should there be one "Relevant Courses" section containing all relevant courses taken at both schools or should I have two separate sections for each college?

Thanks!
