In August 2018, Ofqual announced that it had intervened to adjust the GCSE Science grade boundaries for students who had taken the "higher tier" paper in its new double award science exams and performed poorly, due to an excessive number of students in danger of receiving a grade of "U" or "unclassified".

The Sri Lankan Ordinary Level (O-level) formerly called Senior School Certificate (SSC), is a General Certificate of Education (GCE) qualification in Sri Lanka, conducted by the Department of Examinations of the Ministry of Education. It is based on the Cambridge University Ordinary Level qualification.
The GCE Ordinary-Level qualification is currently administered by the British Council of Sri Lanka Schools (BCS). [8] In the past, this qualification was jointly offered by Cambridge International Examinations and the Ministry of Education in Sri Lanka. The examinations in Sri Lanka are taken very seriously and the exam is considered a starting ...
In biochemistry, steady state refers to the maintenance of constant internal concentrations of molecules and ions in the cells and organs of living systems. [1] Living organisms remain at a dynamic steady state where their internal composition at both cellular and gross levels are relatively constant, but different from equilibrium concentrations. [1]
O-level logo. The General Certificate of Education (GCE) Ordinary Level, also called the O-level or O level, was a subject-based academic qualification.Introduced in 1951 as a replacement for the 16+ School Certificate (SC), the O-level would act as a pathway to the new, more in-depth and academically rigorous A-level (Advanced Level), in England, Wales and Northern Ireland.
Dynamic combinatorial chemistry (DCC); also known as constitutional dynamic chemistry (CDC) is a method to the generation of new molecules formed by reversible reaction of simple building blocks under thermodynamic control. [3] [4] The library [further explanation needed] of these reversibly interconverting building blocks is called a dynamic ...
In a new bottle of soda, the concentration of carbon dioxide in the liquid phase has a particular value. If half of the liquid is poured out and the bottle is sealed, carbon dioxide will leave the liquid phase at an ever-decreasing rate, and the partial pressure of carbon dioxide in the gas phase will increase until equilibrium is reached.
