Changes to GCSEs in Wales, which include fewer science and literature qualifications, puts pupils at a "disadvantage", says some youngsters.
Students studying science at a Y Pant Comprehensive School in Pontyclun have spoken out about their concerns over the new GCSE curriculum in Wales.
Qualifications Wales announced that 26 new and updated GCSEs are being introduced with changes to the content of qualifications and the way they are assessed.
One of the biggest changes is that pupils will no longer study and sit three separate science GCSEs, instead they will either take a double or a single combined science award.
Some six form pupils from Y Pant Comprehensive School told ITV Wales that they feel the changes to the science qualification would put them at a "disadvantage".
One pupil said: "I feel as though it makes us less competitive to students from other countries and it makes applying to Universities a lot harder for us because we don't have as much knowledge before A Levels, and then if they were to look at GCSEs, we're then at a disadvantage."
