Your exam will test your understanding of how democracy works in Scotland and who holds the power. You'll need to know the difference between what the Scottish Parliament can control (devolved powers like education and health) and what stays with Westminster (reserved powers like defence and foreign policy).
The First Minister sits at the heart of Scottish politics, leading the government and representing Scotland. Make sure you can explain why this role is so powerful - they control policy direction, represent Scotland internationally, and lead the largest party in parliament.
💡 Top Tip: Practice explaining both sides of the independence debate. Examiners love questions about why some people want more powers for Scotland whilst others prefer the current system.

Political participation goes way beyond just voting. Citizens have rights (like free speech and standing for election) and responsibilities (like staying informed and respecting the law). You should understand how people can get involved through protests, petitions, or helping with election campaigns.
The criminal justice system in Scotland has two main tracks. Adults go through traditional courts (Sheriff Courts and High Court), whilst young people under 16 usually go to the Children's Hearing System. This system focuses on helping rather than punishing young offenders.
Crime doesn't just affect victims - it impacts entire families and communities. Some groups face higher crime rates due to factors like poverty, location, or lifestyle choices.
💡 Key Point: Remember that the Children's Hearing System is unique to Scotland and emphasises welfare over punishment.

Scottish courts have serious power - they can hand out everything from fines to life sentences. The Sheriff Court deals with most cases, whilst the High Court handles the most serious crimes like murder. Both aim to punish offenders, deter future crime, and protect the public.
The adult court system gets mixed reviews. Supporters argue it provides justice and removes dangerous criminals from society. Critics point out that reoffending rates remain high and prisons are overcrowded.
Meanwhile, the Children's Hearing System takes a completely different approach. It brings together panel members, social workers, and families to create support plans rather than impose punishments.
💡 Exam Strategy: Always give balanced arguments. If a question asks about effectiveness, discuss both successes and failures with specific examples.

The government tackles crime through various strategies - from increasing police numbers to introducing new laws and funding crime prevention programmes. Police Scotland was created in 2013, merging eight regional forces into one national service.
Prison sentences remain controversial. Supporters believe they protect society and deter crime, whilst critics argue they're expensive and don't reduce reoffending. Non-custodial alternatives like community service or electronic tagging are increasingly popular as they're cheaper and often more effective.
The police use both traditional methods (patrols and investigations) and modern technology (CCTV and forensics) to fight crime. However, they face challenges including budget cuts, rising cybercrime, and maintaining public trust.
💡 Remember: You can use the same court information for different questions - just make sure you're answering what's actually being asked.

When studying world powers, you must choose one country and stick with it throughout your exam answers. China, the USA, and Russia are popular choices. Always state your chosen country clearly at the start of each answer.
Different countries have vastly different political systems. Some are democracies where citizens vote for representatives, whilst others are more authoritarian with limited public participation. The level of citizen participation varies enormously between countries.
Political representation works differently across the globe. Some countries have multiple political parties competing for power, whilst others are dominated by a single party. Citizens might participate through voting, protests, or joining political organisations - depending on what their system allows.
💡 Study Tip: Pick one world power and learn it really well rather than trying to remember facts about several different countries.

Every country faces social and economic challenges that affect different groups unequally. These might include poverty, unemployment, inequality, or discrimination. Understanding the root causes helps explain why some citizens struggle more than others.
Governments respond with various policies and programmes designed to tackle these issues. Success rates vary dramatically depending on factors like available resources, political priorities, and the complexity of the problems themselves.
💡 Final Reminder: Use this checklist to track your revision progress. Focus extra time on topics where you haven't ticked all the boxes yet.
