Britannia Royal Naval College at Sandquay, currently the former "Sandown" class minehunter , continues to bear the name "Hindostan". Cadets originally joined the Royal Naval College, Osborne, at the age of 13 for two years' study and work before joining Dartmouth. They studied there for four years there before starting sea training at age 17. RNC Osborne closed in 1923. The entry age for the Naval College was changed to 16 in 1948, and to 17 and 6 months in 1955. Until 1941, Dartmouth was in effect a specialised boarding school, with parents paying fees for tuition and board. During the Second World War,
Royal Swedish Naval Staff College added. Only the coastal artillery course included physics. In higher education courses, special subjects were included, and in some of the general course subjects. In 1926 there were teachers in 18 subjects. As students, the Navy's subaltern officers were commanded in turn; an entry qualification was not needed. The Royal Swedish Naval Staff College was discontinued in 1961 and the Royal Swedish Armed Forces Staff College was formed by merging war colleges of the different military branches, namely the Royal Swedish Army Staff College (established 1878), the Royal Swedish Naval Staff College (established 1898) and the Royal Swedish Air Force
