Quite honestly I don't give a flying fuck! ...Just found out today my daughters has got three A levels, I've always told my kids there are more things to life than passing exams, passing exams don't necessarily bring happiness and wealth so what is the point in worrying! Fine if you get them but don't stress yourself if you don't! Try as hard as you can and see what happens!
That's my advice, take it or leave it!
It's better to be alive and failed your exams than one of the many over the past few years who have got so wound up about the prospect of failure that they have committed suicide!
