It's an absolutely barking decision and a dereliction of duty on the parent's part because it isn't necessary. If Rowan had genuinely discovered an interest she might have waited to get has A levels. In the mid 30s my great uncle didn't take up a grammar school place because the family couldn't afford it and he felt the loss the rest of his life even though there was no alternative. I find it hard not to see Rowan regretting it though no doubt as a Marlow she will delude herself into thinking it her free choice and thus her cross to bear
