In 1901, Reddy graduated with distinction in philosophy and history securing several University prizes. Soon thereafter, he won a Government of India scholarship to study at the University of Cambridge in England. He joined St. John's College at Cambridge in 1902. His career at St Johns College, Cambridge, was no less distinguished than it had been at Madras Christian College. Apart from being a brilliant student, he made his mark as an outstanding speaker and debater. He was elected Secretary of the Liberal Club and later Vice-President of the Union Society. He was the first Indian student to be chosen for that office in the Union Society. When he was the Vice-President of the Union Society, future economist John Maynard Keynes was the Secretary. On 31 October 1905, Reddy invited Gopal Krishna Gokhale to address the Union Society. When Gokhale met Keynes, he instantaneously recognised the genius of Keynes and commented, "You are eminently fitted to be a Finance Member in the Viceroy's Executive Council in India".
