Jamie has just completed her second semester in college. She earned a grade of A in her 5-hour calculus course, a grade of D in her 1-hour sociology course, a grade of A in her 1-hour engineering course, and a grade of F in her 1-hour creative writing course. Assuming that A equals 4 points, B equals 3 points, C equals 2 points, D equals 1 point, and F is worth no points, determine Jamie's grade point average for the semester. Round to two decimal places as needed.
