  2. Academic grading in the United States - Wikipedia

    en.wikipedia.org/wiki/Academic_grading_in_the...

    t. e. In the United States, academic grading commonly takes on the form of five, six or seven letter grades. Traditionally, the grades are A+, A, A−, B+, B, B−, C+, C, C−, D+, D, D− and F, with A+ being the highest and F being lowest. In some cases, grades can also be numerical. Numeric-to-letter-grade conversions generally vary from ...

  3. Module (mathematics) - Wikipedia

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

    Module (mathematics) In mathematics, a module is a generalization of the notion of vector space in which the field of scalars is replaced by a (not necessarily commutative) ring. The concept of a module also generalizes the notion of an abelian group, since the abelian groups are exactly the modules over the ring of integers. [1] Like a vector ...

    Students are given an academic standing; students may be placed on academic probation (where most features from the school were revoked) if they have a low cumulative GPA (usually 1.0, 0.8 in NYP, or 1.4 in SP), or was dismissed from the course of study if they fail to improve their GPA for consecutive semesters, if they have passed the maximum ...

  5. Hilbert's syzygy theorem - Wikipedia

    en.wikipedia.org/wiki/Hilbert's_syzygy_theorem

    Hilbert's syzygy theorem states that, if M is a finitely generated module over a polynomial ring in n indeterminates over a field k, then the n th syzygy module of M is always a free module. In modern language, this implies that the projective dimension of M is at most n, and thus that there exists a free resolution.

    2. The grade grade(M) of a module M over a ring R is grade(Ann M,R), which for a finitely generated module over a Noetherian ring is the smallest n such that Ext n R (M,R) is non-zero. 3. The grade of a module M over a Noetherian local ring with maximal ideal I is the grade of m on I. This is also called the depth of M. This is not consistent ...

    Advanced Level (A-Level) Mathematics is a qualification of further education taken in the United Kingdom (and occasionally other countries as well). In the UK, A-Level exams are traditionally taken by 17-18 year-olds after a two-year course at a sixth form or college. Advanced Level Further Mathematics is often taken by students who wish to ...
