Exam boards have announced that of some exams will be rescheduled to take avoid a clash with the Muslim holy month of Ramadan.
This year, Ramadan falls between June 6 and July 5, which overlaps with a significant proportion of exams, namely Math and English.
Muslims observe Ramadan by fasting during daylight hours, causing concern among teachers that low energy levels could impact performance.
The consideration will mean that subjects taken by large numbers of students, such as GCSE English and Maths could take place before the period begins.
Michael Turner, director general of Joint Council for Qualifications (JCQ), which represents exam boards, said it consulted on the provisional examination timetable every year and considered comments from a wide range of stakeholders including religious groups, schools and colleges.
