Inflation, compound interest, debt and scam signals
Revise the key ideas behind real money: why inflation means the same salary buys a little less every year, how compound interest works, what separates reasonable debt from a trap, and which signals give away a financial scam before you lose a single euro.
Personal finance isn't an abstract syllabus: it's the money decisions every adult ends up making — how much to save, whether to take on debt, where to invest, how to spot an offer that's too good to be true. Understanding it well changes the outcome of an entire life.
The key concepts range from inflation (why idle money loses value) to compound interest (why starting early matters more than the amount), through diversification, the difference between good and bad debt, and the risk signals almost every scam shares: urgency, lack of regulation and promises of guaranteed returns.
Revise these ideas with the exam below, or live an entire life applying them in the Spicy simulator — with its own inflation, job offers and scams to recognise.

The exam poses concrete cases —a frozen salary, an interest-free account over 20 years— so the loss of purchasing power feels tangible, not like a textbook definition.
It stresses that time invested matters more than the starting amount: starting small but early usually beats starting big but late.
Risk signals almost never come alone: unregulated, urgent, 'guaranteed' returns. The exam trains you to spot the combination, not isolated signals.
"A student who thought 'saving it in the account' was the safest option understands, after the inflation question, why that same money will buy less in 20 years — and why investing wisely isn't the same as gambling."
Tricks and techniques to master this topic faster:
Tell inflation (prices rise over time) apart from interest (your money grows over time): the goal is for the second to beat the first.
Before any investment offer, look for at least two risk signals together (urgency, unregulated, 'guaranteed') before deciding — they rarely come alone.
Before taking out a loan, check you have an income source to back it: without a payslip, the debt only grows.
A diversified fund isn't boring by accident: spreading risk across hundreds of companies is precisely what makes it safer long-term.
