University-level education uses a numeric system of grades from two to five, with most grades including 0.5 point increments: 2.0 is the failing grade, 3.0 is the lowest passing grade, followed by 3.5, 4.0 and 4.5, with 5.0 being the highest grade. There is no grade 2.5. A 5.5 or 6.0 is sometimes given as an "exceeds expectations" grade, but this differs among various universities and may be equivalent to 5.0 for some purposes. Similarly "3-" is occasionally (but very rarely) given as a "barely passing" grade, but for all official purposes it is equivalent to 3.0.
