    The National 5 Maths exam, sat on 12 May 2016, in particular Paper 1 (non-calculator), was also criticised by students after being considered much more difficult than previous years. A petition was created by students which was to be sent to the SQA demanding to know why the exam was exceedingly difficult, and it gained over 25,000 signatures. [19]

  3. National Achievement Test - Wikipedia

    en.wikipedia.org/wiki/National_Achievement_Test

    The test is a system-based assessment designed to gauge learning outcomes across target levels in identified periods of basic education. Empirical information on the achievement level of pupils/students serve as a guide for policy makers, administrators, curriculum planners, principles, and teachers, along with analysis on the performance of regions, divisions, schools, and other variables ...

    en.wikipedia.org/wiki/Line_of_greatest_slope

    A mountain biker riding a trail which follows the line of greatest slope, or fall line.. In mountain biking the line of greatest slope defines the fall line, which is the path a trail will follow to descend a hill or mountain with the shortest path, [1] and will also cause the rider to gain the most velocity (assuming brakes are not used, and other factors such as rolling resistance are equal).

  5. Locus (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Locus_(mathematics)

    Each curve in this example is a locus defined as the conchoid of the point P and the line l.In this example, P is 8 cm from l. In geometry, a locus (plural: loci) (Latin word for "place", "location") is a set of all points (commonly, a line, a line segment, a curve or a surface), whose location satisfies or is determined by one or more specified conditions.

  6. Orientation (geometry) - Wikipedia

    en.wikipedia.org/wiki/Orientation_(geometry)

    In geometry, the orientation, attitude, bearing, direction, or angular position of an object – such as a line, plane or rigid body – is part of the description of how it is placed in the space it occupies. [1] More specifically, it refers to the imaginary rotation that is needed to move the object from a reference placement to its current ...

  7. Buffon's needle problem - Wikipedia

    en.wikipedia.org/wiki/Buffon's_needle_problem

    The farthest this end of the needle can move away from this line horizontally in its region is t. The probability that the farthest end of the needle is located no more than a distance l cos θ away from the line (and thus that the needle crosses the line) out of the total distance t it can move in its region for 0 ≤ θ ≤ ⁠ π / 2 ⁠ is ...

  8. No-three-in-line problem - Wikipedia

    en.wikipedia.org/wiki/No-three-in-line_problem

    The no-three-in-line drawing of a complete graph is a special case of this result with =. [12] The no-three-in-line problem also has applications to another problem in discrete geometry, the Heilbronn triangle problem. In this problem, one must place points, anywhere in a unit square, not restricted to a grid. The goal of the placement is to ...

    en.wikipedia.org/wiki/Standard_Grade

    Standard Grades were Scotland's educational qualifications for students aged around 14 to 16 years. Introduced in 1986, the Grades were replaced in 2013 [1] with the Scottish Qualifications Authority's National exams in a major shake-up of Scotland's education system as part of the Scottish Credit and Qualifications Framework overhaul.
