There's been a decline in the number of students taking a GCSE in English Literature.
This summer only 15,000 took the course - compared to around 60,000 studying the English language.
That's despite the Welsh Government expecting students to do both.
Patrick's son is one of those not taking the course.
Teacher Rajvi Glassbrook Griffiths said part of the benefit of taking the literature course are learning those skills you might not be able to see in exam results.
The Education Secretary, Kirsty Williams will be asking Estyn to look at how literature is taught as well as look at the GCSE subjects schools are judged on.
