How to prepare

The early questions will require you to be familiar with Blockly. A tutorial system that also includes some engaging challenges can be found here: blockly-games.appspot.com. Focus especially on the Maze, Turtle and Movie sections.

Unless you are in the Junior age category, you will be required to be familiar with a modern programming language for solving Section 3 problems. Suitable tutorials can be found here: Programming

You will also need to be familiar with the sections required for your age group in the Syllabus

Special tutorials that address this Challenge specifically can be found below

A carefully structured Python tutorial aimed at able beginner programmers can be found here: computer science circles. It is possible for you, and any other students from your school to register on this site and then assign your teacher (or even a student) as your mentor. This person will recieve any requests for help you might make.

 

Example tasks

Example 1: Logo Maker:

A new country has been founded from five small, friendly countries. A program is required that can be used to create its new logo. Using only the blocks supplied, write a program that draws the shape shown.

Example Task

Example 2: Entwined Sequences:

Examine the series of numbers shown below:
        2 1 4 3 8 5 16 7 32 9 64 ...

2 is the 1st number in the series, 1 is the 2nd number in the series, etc.

Using any programming language, create a program that finds the sum of the first 10,000 numbers.
Submit the first 10 digits of the sum as your answer.

Tutorials

This section provides some tutorials that are specific to solving the tasks found in the TCS Oxford Computing Challenges.

1. Blockly Coding Tasks

This type of task is very flexible: Task authors can set problems where a variety of solutions can be given credit for producing the correct answer. These tasks use Function blocks and take this form:

Function Example

How to answer Blockly Coding tasks in the TCS OCC Challenges:
Write all of your code in the function. There is no need to write any code outside of the function. The task author will have provided the necessary parameters and some suitable test data to pass to the function. The Execute block passes these values to the function block as it calls it. (It is OK to change these values to provide yourself with new tests.)

Recommended Practice:
It is not necessary to understand how to create functions to answer these tasks. Your code needs to form a mini-program inside the function block provided. However, there are a few things that you do need to know:

e.g.
