No coursework examplar
Hello sfleming6, I checked the download to see what was wrong and it seems like the notes were uploaded as the coursework examplar. This has now been fixed and the coursework examplar should be downloadable. Most sincere apologies for any inconveniences.

As and a level computer science - h046, h446, specification at a glance, assessment overview.
Students must take all three components to be awarded the OCR A Level in Computer Science.
* Indicates the inclusion of synoptic assessment.
Content overview
Component 01: computer systems.
Students are introduced to the internal workings of the (CPU), data exchange, software development, data types and legal and ethical issues. The resulting knowledge and understanding will underpin their work in component 03.
- The characteristics of contemporary processors, input, output and storage devices
- Types of software and the different methodologies used to develop software
- Data exchange between different systems
- Data types, data structures and algorithms
- Legal, moral, cultural and ethical issues.
Component 02: Algorithms and programming
This builds on component 01 to include computational thinking and problem-solving.
- What is meant by computational thinking (thinking abstractly, thinking ahead, thinking procedurally etc.)
- Problem solving and programming – how computers and programs can be used to solve problems
- Algorithms and how they can be used to describe and solve problems.
Component 03: Programming project
Students are expected to apply the principles of computational thinking to a practical coding programming project. They will analyse, design, develop, test, evaluate and document a program written in a suitable programming language. The project is designed to be independently chosen by the student and provides them with the flexibility to investigate projects within the diverse field of computer science. We support a wide and diverse range of languages.
Students must take both components to be awarded the OCR AS Level in Computer Science.
* Indicates the inclusion of synoptic assessment
Component 01: Computing principles
Students are introduced to the fundamental technical principles of computing.
This component covers:

OCR produces Candidate Sample Work to help centres in both identifying and assessing A Level projects. The Candidate Sample Work covers a range of projects from High to Low grades, giving ideas of how projects have been developed. Links to Candidate Sample Work (Candidate Exemplars) may be found on the H446 webpage, under the Assessment tab.

Divide and conquer is a problem-solving technique used widely across computer science. This strategy can be broken down into three parts: divide, conquer and merge. 'Divide' involves halving the size of the problem with every iteration. Each individual subproblem is solved in the 'Conquer' stage, often recursively.

27. Physics Projectile Modelling Tool. If you are a fan of mechanics, this is your project. One of the many reasons this project is so good is because when programming it, you are forced to simulate a real world environment - in the sense that you program in gravity, terrain, air resistance etc.
A tuple is an ordered set of values of any type. It is immutable, this means that it can't be changed. Elements, therefore, can't be added or removed once it has been created. Tuples are initialised using regular brackets instead of square brackets.
Students must take both components to be awarded the OCR AS Level in Computer Science. Students are introduced to the fundamental technical principles of computing. Legal, moral, cultural and ethical issues. This builds on component 01 to include computational thinking and problem-solving.
Now you may have noticed the exemplars linked below are all over 100 pages, they are for the old H047/H447 spec which emphasised less on coding and more on the report. The new H046/H446 spec is basically the opposite, it favours complexity and coding over the volume of paperwork in the report.

AQA A Level Computer Science Coursework Guide. I've written up a guide on how to tackle the coursework part of the AQA Comp Sci course. It's a real pain since the examiners don't give you much to go on. I was quite lucky to have the right mix of random-ass diagrams and paragraphs to get 67/75 last year so I've written about what I did.
