I would recommend taking either finite (MATH-M 118) or calc (MATH-M 119) over the summer rather than gen eds. Many gen ed classes are pretty easy and grade favorably.
I would go through the list of gen eds and find several that sound interesting, then look up the grade distribution and see how it looks. If you don’t plan on studying abroad or taking a foreign language, I would highly recommend taking 2 classes that double count for World Culture and Arts and Humanities. I took Ancient Greek Culture (CLAS-C 101) and Intro to the Old Testament (REL-A 210). They both double count and were pretty easy. Many students take Intro to Psychology (PSY-P 101) for natural science, and I have heard it’s pretty easy.
