In short - Yes. Most people are aware that there are a number of
"core" subjects which students need to study in order to gain good
college and university places, and to succeed in the work place.
Typically, GCSE English, GCSE Maths and the GCSE dual Science
syllabus are the "big three" subjects in this respect, and most
employers and further or higher education establishments stipulate
grade C or above for GCSE Maths, GCSE English and GCSE dual science
as the syllabus for each of these subjects is considered to teach
students skills which are vital for all aspects of life. For more
