Problem: Background: Robert Stewart, 2nd Marquess of Londonderry,  (18 June 1769 - 12 August 1822), usually known as Lord Castlereagh, which is derived from his courtesy title Viscount Castlereagh, (UK:  KAH-s@l-rey), was an Irish/British statesman. As British Foreign Secretary, from 1812 he was central to the management of the coalition that defeated Napoleon and was the principal British diplomat at the Congress of Vienna. Castlereagh was also leader of the British House of Commons in the Liverpool government from 1812 until his suicide in August 1822. Early in his career, as Chief Secretary for Ireland, he was involved in putting down the Irish Rebellion of 1798 and was instrumental in securing the passage of the Irish Act of Union of 1800.
Context: Stewart had recurring health problems throughout his childhood, and his family elected to send him to The Royal School, Armagh, rather than to England for his secondary education. At the encouragement of Charles Pratt, first Earl of Camden, who took a great interest in him and treated him as a grandson by blood, he later attended St. John's College, Cambridge (1786-87), where he applied himself with greater diligence than expected from an aristocrat and obtained first class in his last examinations. He left Cambridge due to an extended illness, and after returning to Ireland did not pursue further formal education.  In 1790, Stewart was elected as a Member of the Irish Parliament for Down in one of the most expensive elections in Irish history. Though for a time he was associated with the Northern Whig Club, he entered the Irish House of Commons as an Independent. He ran on a platform supporting Whig principles of electoral reform and opposing the Irish policies of the British Government. But even from the outset of his career, he was a personal supporter of the Prime Minister, William Pitt. Stewart was a lifelong advocate of Catholic concessions, though his position on the specific issue of Catholic Emancipation varied depending on his assessment of the potential repercussions on other policy priorities.  When war with France forced British Government attention on Ireland as a possible place of French invasion, the Irish Volunteers, seen as a potential source of disaffection, were disbanded by Dublin Castle, and a reorganised Militia was created in 1793. Stewart enrolled as an officer, a matter of course for a young Protestant aristocrat, and served as Lieutenant Colonel under the command of his wife's uncle, Thomas Conolly. Between Stewart's attendance to his militia duties, his pursuit of cultural, family and political interests in London, two trips to the Continent (in 1791, when he visited revolutionary Paris, and 1792), and the courtship of his wife whom he married in 1794, his life during this period was not centred on the activities of the Irish House of Commons, where he was listened to with respect but where he was not yet an important player. He was also beginning to disappoint some of his more radical original supporters in his constituency. As the French Revolution grew more bloody and Ireland more rebellious, Stewart increasingly worried about Ireland's future if the threats from France succeeded in breaking Ireland's links to Britain. He became further inclined to support not only Pitt personally but the British Government, even when he did not approve of a specific line taken in Irish policy.  In 1794, partly as a result of the promotion of Stewart's interests by his Camden connections, he was offered the Government-controlled seat of Tregony in Cornwall, where he was elected to the British House of Commons on a similar platform of reform principles and support for Pitt, on whose side he sat in Westminster. In 1796, he transferred to a seat for the Suffolk constituency of Orford, which was in the interest of his mother's family, the Seymour-Conways (Marquess of Hertford).
Question: Did he have other accomplishments at school?
Answer: after returning to Ireland did not pursue further formal education.

Background: The King and I is the fifth musical by the team of composer Richard Rodgers and dramatist Oscar Hammerstein II. It is based on Margaret Landon's novel, Anna and the King of Siam (1944), which is in turn derived from the memoirs of Anna Leonowens, governess to the children of King Mongkut of Siam in the early 1860s. The musical's plot relates the experiences of Anna, a British schoolteacher hired as part of the King's drive to modernize his country. The relationship between the King and Anna is marked by conflict through much of the piece, as well as by a love to which neither can admit.
Context: Mongkut, King of Siam, was about 57 years old in 1861. He had lived half his life as a Buddhist monk, was an able scholar, and founded a new order of Buddhism and a temple in Bangkok (paid for by his half-brother, King Nangklao). Through his decades of devotion, Mongkut acquired an ascetic lifestyle and a firm grasp of Western languages. When Nangklao died in 1850, Mongkut became king. At that time, various European countries were striving for dominance, and American traders sought greater influence in Southeast Asia. He ultimately succeeded in keeping Siam an independent nation, partly by familiarizing his heirs and harem with Western ways.  In 1861, Mongkut wrote to his Singapore agent, Tan Kim Ching, asking him to find a British lady to be governess to the royal children. At the time, the British community in Singapore was small, and the choice fell on a recent arrival there, Anna Leonowens (1831-1915), who was running a small nursery school in the colony. Leonowens was the Anglo-Indian daughter of an Indian Army soldier and the widow of Thomas Owens, a clerk and hotel keeper. She had arrived in Singapore two years previously, claiming to be the genteel widow of an officer and explaining her dark complexion by stating that she was Welsh by birth. Her deception was not detected until long after her death, and had still not come to light when The King and I was written.  Upon receiving the King's invitation, Leonowens sent her daughter, Avis, to school in England, to give Avis the social advantage of a prestigious British education, and traveled to Bangkok with her five-year-old son, Louis. King Mongkut had sought a Briton to teach his children and wives after trying local missionaries, who used the opportunity to proselytize. Leonowens initially asked for $150 in Singapore currency per month. Her additional request, to live in or near the missionary community to ensure she was not deprived of Western company, aroused suspicion in Mongkut, who cautioned in a letter, "we need not have teacher of Christianity as they are abundant here". King Mongkut and Leonowens came to an agreement: $100 per month and a residence near the royal palace. At a time when most transport in Bangkok was by boat, Mongkut did not wish to have to arrange for the teacher to get to work every day. Leonowens and Louis temporarily lived as guests of Mongkut's prime minister, and after the first house offered was found to be unsuitable, the family moved into a brick residence (wooden structures decayed quickly in Bangkok's climate) within walking distance of the palace.  In 1867, Leonowens took a six-month leave of absence to visit her daughter Avis in England, intending to deposit Louis at a school in Ireland and return to Siam with Avis. However, due to unexpected delays and opportunities for further travel, Leonowens was still abroad in late 1868, when Mongkut fell ill and died. Leonowens did not return to Siam, although she continued to correspond with her former pupil, the new king Chulalongkorn.
