Year 11 is the year in which you take your GCSEs (unless of course a deadly virus sweeping the world results in them getting cancelled... as if that would happen)
In Year 11 you have the same classes and teachers as Year 10, and all in all Year 11 is rather similar to Year 10 just 1480x more stressful.
The current Year 11 joined in 2016, and their Head of Year is Mrs Bowdler.
The last year to have a Halloween disco and the first to have the same Head of Year all 5 years.
Note: Rather than saying "11S" for example, we use "16S" so that we don't need to update the year group each new school year
