Moleskine is a brand of notebook that comes in various formats, sizes, and papers. The covers are usually black leather (some special editions have silk, for instance, and diaries come in red) and there is an elastic band for keeping it closed.
The GPA that reflects those course choices is the weighted GPA and the GPA that considers all courses as equal is the unweighted GPA. With a few exceptions (University of California schools, notably), schools all use unweighted GPA in college admissions decisions.
3.0 = B (good, or above average) 4.0 = A (excellent) Thus, a GPA of 3.5 would be equivalent to a B+. The GPA can be particular to a specific semester or cumulative. However, when calculating a semester GPA there are other factors involved to include the grade and the quality points assigned to that grade.
