[3] [4] In June 2011 Edexcel announced that the AEA was being extended further for mathematics, until June 2015, which was later extended until 2018. [ 5 ] In 2018, Edexcel introduced a new specification, meaning the Advanced Extension Award in mathematics would continue to be available to students in 2019 and beyond, as a qualification aimed ...
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
The Singapore-Cambridge General Certificate of Education Ordinary Level (or Singapore-Cambridge GCE O-Level) is a GCE Ordinary Level examination held annually in Singapore and is jointly conducted by the Ministry of Education (MOE), Singapore Examinations and Assessment Board (SEAB) and the University of Cambridge Local Examinations Syndicate (UCLES).

The teenage stage isn’t easy for anyone, whether you’re the teen or the parent. And that’s not only true when it comes to human teenagers, but canine ones, too.
Prince William has no doubt given Kate Middleton many gifts she cherishes over their more than two decades together — but one gift was apparently so “awful” that he’ll never live it down ...
In supramolecular chemistry, chemical species are structures created by forming or breaking bonds between molecules, such as hydrogen bonding, dipole-dipole bonds, etc. [3] These types of bonds can determine the physical property of chemical species in a liquid or solid state.
Among the problems that he sees for a spinoff is the fact that the family is so close and tight-knit that it’s almost impossible to do a show without the whole family showing up.
Homologous series are not unique to organic chemistry. Titanium , vanadium , and molybdenum oxides all form homologous series (e.g. V n O 2 n − 1 for 2 < n < 10), called Magnéli phases , [ 9 ] as do the silanes , Si n H 2 n + 2 (with n up to 8) that are analogous to the alkanes, C n H 2 n + 2 .
