AQA · 8525LearningP is independent of AQA. Use the current official documents for assessment requirements.
Try three different Computer Science skills from this AQA route. See what went right, understand a mistake, and find a useful next step.
A small preview of how LearningP turns answers into a clearer learning picture for students and parents.
An algorithm is a sequence of steps that can be followed to complete a task. A computer program is an implementation of an algorithm in executable code.
Both requirements must hold: the door is open and disarmed is False. Applying NOT to disarmed and combining with AND gives the required expression.
Authentication verifies users, MAC filtering controls listed devices and a firewall applies traffic rules. Combining controls provides defence in depth, although none guarantees complete security.
These tiles show your answers to three questions. They are a starting point, not a mastery score or grade prediction.
Correct answer: It is an algorithm because it gives ordered steps for completing a task
An algorithm is a sequence of steps that can be followed to complete a task. A computer program is an implementation of an algorithm in executable code.
Correct answer: doorOpen AND NOT disarmed
Both requirements must hold: the door is open and disarmed is False. Applying NOT to disarmed and combining with AND gives the required expression.
Correct answer: Each controls a different aspect of access, so layered controls reduce reliance on one defence
Authentication verifies users, MAC filtering controls listed devices and a firewall applies traffic rules. Combining controls provides defence in depth, although none guarantees complete security.
For parents: look at the explanation together. A correct answer is encouraging; a missed answer gives you something specific to work on. Broader practice over time is needed to understand progress.
AQA requires informal comparison of time efficiency. Fewer processing steps for the same inputs can support a time-efficiency comparison, but it says nothing automatically about memory or language level.
Watch for: Do not describe Fundamentals of algorithms vaguely. Trace the algorithm, data or system state precisely and test boundary or failure cases.
A count-controlled loop is appropriate when the number of repetitions is known in advance. A condition-controlled loop is better when repetition depends on a changing condition.
Watch for: Do not describe Programming vaguely. Trace the algorithm, data or system state precisely and test boundary or failure cases.
Hexadecimal is a compact human-readable notation: one hex digit maps exactly to four binary bits. Changing the notation does not reduce the underlying number of stored bits.
Watch for: Do not describe Fundamentals of data representation vaguely. Trace the algorithm, data or system state precisely and test boundary or failure cases.
Cloud storage is located remotely and normally reached through a network. Connectivity, provider availability, privacy and ongoing cost can therefore be disadvantages compared with local control.
Watch for: Do not describe Computer systems vaguely. Trace the algorithm, data or system state precisely and test boundary or failure cases.
Authentication verifies users, MAC filtering controls listed devices and a firewall applies traffic rules. Combining controls provides defence in depth, although none guarantees complete security.
Watch for: Do not describe Fundamentals of computer networks vaguely. Trace the algorithm, data or system state precisely and test boundary or failure cases.
Biometric access checks a physical characteristic, while email confirmation alerts and requires action through another account. Layering them reduces dependence on a single control.
Watch for: Do not describe Cyber security vaguely. Trace the algorithm, data or system state precisely and test boundary or failure cases.
A foreign key stores a primary-key value from another table, creating a relationship between each order and its customer. It may repeat because one customer can have several orders.
Watch for: Do not describe Relational databases and SQL vaguely. Trace the algorithm, data or system state precisely and test boundary or failure cases.
Responsible disclosure gives the organisation an opportunity to reduce harm while avoiding unauthorised access or premature release of exploit details. Exact legal duties depend on jurisdiction and authorisation.
Watch for: Do not describe Ethical, legal and environmental impacts vaguely. Trace the algorithm, data or system state precisely and test boundary or failure cases.

Version 1.3, 16 June 2025; first exams 2027; current checked 27 August 2026
Source checked: 2026-08-27. The current official specification controls assessment requirements and option choices.
Yes. This page offers three original questions from three different skills on this exact course. Each answer has an explanation, followed by a sample heatmap showing what was correct and what to revisit. No account is needed, and taster answers are not saved.
It shows the outcome of these three answers and gives a specific skill to discuss or practise next. It is not a full assessment, a mastery score or a grade prediction. Broader practice over time is needed to understand progress.
LearningP currently maps 8 assessed areas for specification 8525. The visible topic map below is derived from the verified route; the current official specification remains controlling.
The verified source bank contains 164 original LearningP question records for this route. Every mapped area meets the current publication minimum and passed the latest blocker and review audit.
No. LearningP uses official specifications and assessment materials to map content and demand, while its practice questions and explanations are independently authored.
No. LearningP reports practice evidence, coverage, strengths and gaps. It does not guarantee or automatically predict examination outcomes.
