Although I'm not surprised that many of you oppose this and A levels appear internationally competitive, I think your all forgetting that right now about 50% are headed to university (most doing A levels) and there are far more graduates than skilled jobs that require a degree. Further, every year sees grade inflation and a teaching and student lobby who cry when they try and arrest this.
They need to provide a disincentive to A levels without actually limiting the number that can do them and so adding more work is likely a way to do this, especially if it makes things harder.
It's also a good way to score a win in international league tables. Remember that people whined about the Gove reforms but in the end that was broadly a success statistically.
