Gordon Ramsey has been bursting himself with pride all over social media and the press about his eldest son (Jack!) who has just passed out as a Royal Marine, having completed the Commando Course, well recognised as one of the toughest military training courses in the world. It requires toughness, fitness, mental strength, flexibility, and the ability to dig deep and work as a team. His son had the ability and results to go to university and this is what he chose.
I don't think that Jack's elder brother went to university but seems to be doing well as an RAF officer.
Jack didn't go to university but she didn't stick with anything either. She couldn't work as part of a team and she doesn't have any kind of toughness, mental or otherwise. If she really wanted to, she could do a pre-uni course in lieu of qualifications, start with the Open University, or go to a local college for an HNC/HND and then transfer to university. None of which she will do as it involves graft rather than grift.
It would be interesting to see what the RAF interview board made of her and on what grounds they refused her.
