Prior to this, around 1996, Combined Science GCSEs were available as an alternative to three separate Sciences for many exam boards. Combined Science consists of either Higher Tier (HT) or Foundation Tier (FT) papers AQA offer two different specifications entitled Synergy and Trilogy. [2]
Following recent changes, a student can go for one of two routes if taking AQA combined science: trilogy or synergy. [34] In trilogy, science is delivered in the three traditional parts of biology, chemistry and physics. The trilogy specification document outlines topics for each science part and practicals are specified. The trilogy GCSE exam ...

Over time, the validity of this system was questioned because, rather than reflecting a standard, norm referencing simply maintained a specific proportion of candidates at each grade, which in small cohorts was subject to statistical fluctuations in ...
In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field.
Latin and Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities.
Shoelace scheme for determining the area of a polygon with point coordinates (,),..., (,). The shoelace formula, also known as Gauss's area formula and the surveyor's formula, [1] is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by their Cartesian coordinates in the plane.

In many popular versions of axiomatic set theory, the axiom schema of specification, [1] also known as the axiom schema of separation (Aussonderungsaxiom), [2] subset axiom [3], axiom of class construction, [4] or axiom schema of restricted comprehension is an axiom schema. Essentially, it says that any definable subclass of a set is a set.
