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".

The GCSE combined science A exam is made up of six papers (each one hour and ten minutes): two each for biology, chemistry and physics respectively. In combined science B, the science curriculum is delivered in four parts: biology, chemistry, physics and combined science.
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.
In these cases, a useful diagnostic adjunct involves measuring the nasal transepithelial potential difference (i.e. the charge on the respiratory epithelial surface as compared to interstitial fluid). Individuals with cystic fibrosis have a significantly more negative nasoepithelial surface than normal, due to increased luminal sodium absorption.
2023: OCR was criticised by pupils and teachers for the level of difficulty in Paper 2 of the Computer Science GCSE. [22] [23] Students took to social media to express concern at the disparity between Paper 1 and Paper 2, as well as the change in style of the paper. OCR assured students that the final mark scheme would reflect the different ...

The same principle applies to voltage in cell biology. In electrically active tissue, the potential difference between any two points can be measured by inserting an electrode at each point, for example one inside and one outside the cell, and connecting both electrodes to the leads of what is in essence a specialized voltmeter.
In June, Paper 3 of the Mathematics GCSE (Higher Tier, 1MA1/03) appeared to contain an exam question which was published in an AQA (another British exam board) Further Mathematics textbook. The exam question had the same diagram , values and answer as the question in the textbook.
