Conclusion

The concluding section is concerned with summarising clearly and concisely what you achieved, relative to the assigned exercise. If you have learned anything new during the exercise, you can state that here too.

Do not make any bald or simplistic claims to the effect that a program (or function etc.) "works" - except insofar as that is backed up by test results you have already given in the Development section. A program that merely compiles without error is a very long way indeed from one that works. Keep this distinction clear in your mind when writing this section. Do not try to pad this section out, or disguise some shortfall in completing the exercise. The marks here go for clarity, and honesty, not actual achievement!
