Please complete the final essay question. Using the mark scheme, I’d like you to reverse engineer the question by creating a mindmap and essay. The mark sheme only shows the basic points & top band marks – how can you use this to create an excellent essay?

Pseudocode for projects & Programming paper.

Working in pairs is really useful for getting to grips with pseudocode. Good practice for this is to take a program that you can code together with one writing pseudocode & the other using the pseudocode to program. After minutes, swap roles. This would work really well with you and Elly working together.

We used the OCR Pseudocode Guide today which you should find really useful for your Project work.
