On 17 August, Ofqual and Secretary of State for Education Gavin Williamson agreed that grades would be reissued using unmoderated teacher predictions. [24] [25] As a result, there was an annual increase by more than 10 percentage points in the number of top grades awarded (from 25.2% to an estimated 37.7%), [26] the biggest increase for at ...
Combined Science results in two GCSEs. Those with GCSEs in Combined Science can progress to A Levels in all of the three natural science subjects. 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 ...
The ultraviolet catastrophe, also called the Rayleigh–Jeans catastrophe, was the prediction of late 19th century to early 20th century classical physics that an ideal black body at thermal equilibrium would emit an unbounded quantity of energy as wavelength decreased into the ultraviolet range. [1]: 6–7 The term "ultraviolet catastrophe ...
SyRI. v. t. e. In 2020, Ofqual, the regulator of qualifications, exams and tests in England, produced a grades standardisation algorithm to combat grade inflation and moderate the teacher-predicted grades for A level and GCSE qualifications in that year, after examinations were cancelled as part of the response to the COVID-19 pandemic.

State schools in Scotland use the Scottish Qualifications Certificate instead. However, private schools in Scotland ...
The Standard Model is renormalizable and mathematically self-consistent, [1] however despite having huge and continued successes in providing experimental predictions it does leave some unexplained phenomena. [2] In particular, although the physics of special relativity is incorporated, general relativity is not, and the Standard Model will ...
The cosmic microwave background (CMB, CMBR), or relic radiation, is microwave radiation that fills all space in the observable universe. With a standard optical telescope, the background space between stars and galaxies is almost completely dark. However, a sufficiently sensitive radio telescope detects a faint background glow that is almost ...
