Time in lessons is now given to preparation and revision for the Early Entry GCSE examination.

All students will be sitting an exam, either as a certificated, external GCSE examination, or as a “mock” internal End of Year exam.

##### Subject Overview:

In Year 10 our Higher students are stretched even further. We cover as much of the curriculum as possible and all our students cover enough material to access a grade 9 at the end of Year 10.

Students who gain the top grades will be able to do a 1-year GCSE in Further Maths in Year 11. Others will get the opportunity to improve their GCSE grade at the end of Year 11.

This approach to Early Entry and using it as a 'springboard' into Year 11 has proven very successful over the years.

##### Assessments:

In Year 10 there are end of unit assessments and in the summer students will either sit the Early Entry Higher GCSE maths exam or will sit an internal End of Year exam.
