Competition Documentation Extract
Students are allowed access of up to 20 sides of language notes/hints in the competition. We suggest this particular extract (with permission) from Coding Club Core-Cards* which we’ve combined with an overview for use of input(), some more helpful snippets and some blank pages at the back which should be completed before the competition if students wish to use these.
For some systematic preparation, students using Python may wish to look at:
- This new selective introduction to Python under development: https://www.pythonsponge.com/
- This step-by-step Python tutorial: https://cscircles.cemc.uwaterloo.ca/
- This more advanced but useful Python two page hints sheet
- The extensive but very comprehensive W3 Schools Python introduction (and their introductions to other languages): https://www.w3schools.com/python/
For simpler hackerrank starter problems, this short competition that we wrote for a previous Science Week might be worthwhile: https://www.hackerrank.com/science-week-code-sprint
If users have any similar suggestions for other languages, please let us know.
Paul Baker (Head of Computing and Digital Strategy) and Dave Gwilt (Head of Computer Science) both teach at The Perse School, Cambridge. Paul Walter (Head of Computing) teaches at MCS Oxford. Thanks also goes to Perse colleagues Gyorgy Denes, Iain Attenborough and Stuart Gray who frequently assist with question suggestions and testing.

Competition topic overview
The main point of the problems are to develop algorithmic / computational thinking.
- Logical and Algorithmic Thinking
- Decomposition and Abstraction
- Pattern Identification
- Debugging and continual testing
Language constructs typically used include:
- type conversion (including string, integer, float, Boolean)
- basic string processing (inc. letter by letter iteration, find/replace, reversing…)
- arrays / lists+
Level 4 problems may have one or two test cases which test the efficiency of the solution within the timeout allowed. * Please note that input prompts / additional output must not be included in solutions because of the auto-marking. + Nested lists, dictionaries, 2D arrays or other structure might be useful on some higher level problems.
We integrate with the UKCT Challenges competition progression pathway: please do find out more about the Bebras and Oxford Computing Challenges (which sit earlier in the pathway) and The British Informatics Olympiad which is the next step on for older students.
