Since 1910, successful students in the examinations have been told their rankings privately, and not all Senior Wranglers have become publicly known as such. In recent years, the custom of discretion regarding ranking has progressively vanished, and all Senior Wranglers since 2010 have announced their identity publicly. The youngest person to be Senior Wrangler is probably Arran Fernandez, who came top in 2013, aged 18 years and 0 months. The previous youngest was probably James Wilkinson in 1939, aged 19 years and nine months. The youngest up to 1909 were Alfred Flux in 1887, aged 20 years and two months and Peter Tait in 1852, aged 20 years and eight months. Two individuals have placed first without becoming known as Senior Wrangler. One was the student Philippa Fawcett in 1890. At that time, although the University allowed women to take the examinations, it did not allow them to be members of the University, nor to receive degrees. Therefore they could not be known as 'Wranglers', and were merely told how they had performed compared to the male candidates, for example, "equal to the Third Wrangler", or "between the Seventh and Eighth Wranglers". Having gained the highest mark, Fawcett was declared to have finished "above the Senior Wrangler". The other was the mathematics professor George Pólya. As he had contributed to reforming the Tripos with the aim that an excellent performance would be less dependent on solving hard problems and more so on showing a broad mathematical understanding and knowledge, G.H. Hardy asked Pólya to sit the examinations himself, unofficially, during his stay in England in 1924–5. Pólya did so, and to Hardy's surprise, received the highest mark, an achievement which, had he been a student, would have made him the Senior Wrangler. Derived uses of the term Senior Wrangler's Walk is a path in Cambridge, the walk to and along which was considered to be sufficient constitutional exercise for a student aspiring to become the Senior Wrangler. The route was shorter than other walks, such as Wranglers' Walk and the Grantchester Grind, undertaken by undergraduates whose aspirations were lower. Senior Wrangler sauce is a Cambridge term for brandy butter, a type of hard sauce made from brandy, butter, and sugar, traditionally served in Britain with Christmas pudding and warm mince pies. Senior Wrangler is also the name of a solitaire card game, alternatively known as Mathematics and Double Calculation, played
