GCSE Bitesize was launched in January 1998, covering seven subjects. For each subject, a one- or two-hour long TV programme would be broadcast overnight in the BBC Learning Zone block, and supporting material was available in books and on the BBC website. At the time, only around 9% of UK households had access to the internet at home.
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".

In New Zealand, Year 3 is the third full year of compulsory education. Children are aged seven or eight in this year group. When children start school, they begin in New Entrants and typically move to Year 1 when the next school year begins. [2] Year 3 pupils are usually educated in Primary schools or in Area schools. [3]

[4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.

[ 9 ] [ 10 ] Many school teachers now incorporate these videos into their classes, [ 4 ] [ 9 ] and the professor has even recorded video responses to some of ...
A sphere of radius r has surface area 4πr 2.. The surface area (symbol A) of a solid object is a measure of the total area that the surface of the object occupies. [1] The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of arc length of one-dimensional curves, or of the surface area for polyhedra (i.e., objects with ...
