[31] [36] In Edexcel's combined science specification document the curriculum is delivered in the three traditional disciplines of biology, chemistry and physics, but in Eduqas's , the science curriculum is divided into four parts: Concepts in Biology, Concepts in Chemistry, Concepts in Physics and Applications in Science. The Eduqas combined ...
Additionally, corroles and their metal complexes have been demonstrated to be useful as imaging agents in tumor detection, [8] oxygen sensing, [9] for prevention of heart disease, [10] in synthetic chemistry as oxo, imido, and nitrido transfer agents, [11] and as catalysts for the catalytic reduction of oxygen to water, [12] and hydrogen ...
The O grade was equivalent to a GCE Ordinary Level pass which indicated a performance equivalent to the lowest pass grade at Ordinary Level.. 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 ...
It assesses candidates' competence in science practical skills over an appropriate period of time that the candidates are offered the subject, [1] and constitutes 20% of the overall marks for the subject. SPA replaced the traditional Practical Examination, which was normally conducted at the end of the 2-year course, in 2006.
Most IGCSE subjects offer a choice of tiered examinations: Core or Extended papers (in Cambridge International), and Foundation or Higher papers (in Edexcel). This is designed to make IGCSE suitable for students with varying levels of ability. In some subjects, IGCSE can be taken with or without coursework.
The Department for Education has drawn up a list of core subjects known as the English Baccalaureate for England based on the results in eight GCSEs, which includes both English language and English literature, mathematics, science (physics, chemistry, biology, computer science), geography or history, and an ancient or modern foreign language.
The Maths stream includes four main subjects: Combined Mathematics, Physics, Chemistry, and Information and Communication Technology (ICT). Under the recent syllabus, candidates can choose between Chemistry and ICT, although Combined Mathematics and Physics are mandatory.
Structure of N-bromosuccinimide, a common brominating reagent in organic chemistry. Like the other carbon–halogen bonds, the C–Br bond is a common functional group that forms part of core organic chemistry. Formally, compounds with this functional group may be considered organic derivatives of the bromide anion.
