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".

Some organizations responsible for holding exams have made past exam papers commercially available by either publishing the papers by themselves or licensing a publisher to do the same. For example, UPSC papers in India, SAT papers in U.S. and GCSE and A level papers in UK are being sold, as well as other exams worldwide.
The new combined science from CCEA since the GCSE reforms retains the same name as its predecessor. [37] The specification document presents the science curriculum in the traditional disciplines of biology, chemistry and physics. The exam is the most extensive of the GCSE science boards; made up of nine papers and three practical exams.
However the exam papers of the GCSE sometimes had a choice of questions, designed for the more able and the less able candidates. When introduced the GCSEs were graded from A to G, with a C being set as roughly equivalent to an O-Level Grade C or a CSE Grade 1 and thus achievable by roughly the top 25% of each cohort.

Sometimes incorrectly known as the Advanced Ordinary Level, the AO-Level syllabus and examination both assumed a higher degree of maturity on the part of candidates, and employed ...
[106] [107] In tropical grasses, including maize, sorghum, sugarcane, Bermuda grass and in the dicot amaranthus, leaf photosynthetic rates were around 38−40 μmol CO 2 ·m −2 ·s −1, and the leaves have two types of green cells, i.e. outer layer of mesophyll cells surrounding a tightly packed cholorophyllous vascular bundle sheath cells.
Periodic tables usually at least show the elements' symbols; many also provide supplementary information about the elements, either via colour-coding or as data in the cells. The above table shows the names and atomic numbers of the elements, and also their blocks, natural occurrences and standard atomic weights. For the short-lived elements ...
