What is not expected to be syntactically perfect according to the exam board?

• The video production quality

• The textbook content

• Candidates' code

• The exam questions

Answer explanation

Candidates' code is not expected to be syntactically perfect according to the exam board, as they are often assessed on logic and problem-solving skills rather than perfect syntax.

Where can algorithms and data structures from component one appear again?

• In the component two exam on algorithms and programming
