I never understood the point of requiring literature courses, since software engineers will never need that anyway. You may want to consider taking the course at a community college over the summer, and transferring the credit. If you do poorly, you can opt not to transfer without hurting your GPA, and community college courses are easier from my experience. Since you'll be taking it during the summer, you'll have more time to focus on it alone. Hopefully that will work for you.
Also, the answer to one of our math problems this morning was 333, so I was forced to giggle a little.
