    However, further complicating the computation is the fact that American schools typically meet 180 days, or 36 academic weeks, a year. A semester (one-half of a full year) earns 1/2 a Carnegie Unit. [1] The Student Hour is approximately 12 hours of class or contact time, approximately 1/10 of the Carnegie Unit (as explained below).

  3. Full-time equivalent - Wikipedia

    This allows employers to adopt a single metric for comparison with the full-time average. For example, a full week of 40 hours has an FTE value of 1.0, so a person working 20 hours would have an FTE value of 0.5. Certain industries may adopt 35 hours, depending on the company, its location and the nature of work.

    en.wikipedia.org/wiki/Trapezoidal_rule

    In calculus, the trapezoidal rule (also known as the trapezoid rule or trapezium rule) [a] is a technique for numerical integration, i.e., approximating the definite integral: (). The trapezoidal rule works by approximating the region under the graph of the function f ( x ) {\displaystyle f(x)} as a trapezoid and calculating its area.

    en.wikipedia.org/wiki/Academic_grading_in_Serbia

    In elementary schools and secondary schools, a five-point grading scale is used: 5 (excellent) 4 (very good) 3 (good) 2 (sufficient) is the lowest passing grade. 1 (insufficient) is the lowest possible grade, and the failing one. In addition, descriptive grades are used to grade a student's conduct and religious or civic education.
