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.
Generally speaking, if the GPA is greater than 3.4 (for undergrad) and 3.6 (for grad student) on a scale of 4.0, definitely go ahead an put that GPA on your resume. GPA between 3.0 - 3.4 or 3.6 falls in the grey zone. GPA below 3.0 will most likely hurt your first impression.
