Welcome to Extended Science GCSE

The Science Department at The Westgate School offers the widest curriculum across Key Stages 4 and 5, achieving excellent outcomes for students. Our dedicated team of teachers and technicians aspire to give the students a fantastic learning experience both practically and theoretically. Both GCSE Combined and Extended Science courses consist of a wide range of key concepts in Biology, Chemistry and Physics, including many cross curricular links with Maths and English. All students will take six science exams at the end of Year 11, with separate science exams covering more content and a duration of 1 hour and 45 minutes each.  All students will develop their practical skills by completing a series of core practicals that could be examined at the end of the course. Students who enrol in GCSE Extended Science will complete a greater number of practical tasks that are covered in A Level and BTEC L3 Sciences. The specification can be viewed here:

Do I have to study separate sciences to pursue medicine or other scientific careers? 

Both GCSE courses provided opportunities for students who want to pursue a scientific career. The aim of studying GCSE separate sciences is to help bridge the gap between GCSE and A Level/BTEC L3 Sciences. Additionally, it is a course for those students who enjoy a challenge and are enthusiastic about Science. 

How is the course different to GCSE Combined Science? 

Students will complete all the content contained within Combined Science, plus additional units or extra lessons found within the core units. For example, there are 17 units in combined Chemistry but there are 26 units in separate Chemistry. 

Is there any coursework or internal assessments? 

There are no elements of coursework or mandatory internal assessments. The students must partake in a series of core practical tasks that could be assessed in their GCSE exams. Everyone is provided with a free lab book to write up their findings and answer exam style questions. This will be marked, corrected and feedback given within lessons. 

How many exams are there and how long are they? 

At the end of the course, students will sit six exams (two Biology, two Chemistry and two Physics) that are all 1 hour and 45 minutes long. 

How many lessons of science will I have a week? 

There will be seven science lessons allocated on the timetable. You may have more than one science lesson in a day. 

How much Maths is there in each subject? 

Each science will test student’s ability on arithmetic, handling data, algebra, geometry, plotting and analysing graphs. There is a minimum mathematical requirement of 10% in Biology, 20% in Chemistry and 30% in Physics. The aim of this is to prepare students for the mathematical demand in A Level Science.
