Source release: Oxford examination archive. The cover dates this examination to 17 June 2011, 9.30–11.00am. The unlettered requests in Question 1 are covered together in its parent Solution, with separate Solutions for its two numbered interval tests. Questions 2 and 3 each have one complete Solution.

Original solutions to both sections and all six questions of the Approximation Theory and Finite Element Methods paper sat on 10 June 2010. Source: released Mathematics papers, Part C 2007 11.pdf. Question 1 gives the sharp bound for the printed functional; question 4 distinguishes the printed normal condition from the conormal condition needed for the requested symmetric variational construction. Statements are not reproduced.

Original solutions to all three questions of the Approximation of Functions paper sat on 16 June 2011. Source: released Mathematics papers, Part C 2007 11.pdf. Question 3 includes a counterexample to the unqualified printed endpoint exchange rule and the corrected rule. Statements are not reproduced.

Source release: Oxford examination archive release thread. The four-page scan is from pages 434–437 of the released Part C bundle. The cover identifies paper C6.3b, formal codes DMAC 2B68 and DMCO 2B68, and Thursday 9 June 2011.
