Connect Prevention First to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Prevention First from memory before moving on to harder problems.

Reference excerpt

Prevention First is a nonprofit resource center based in Springfield, Illinois, committed to building and supporting healthy, drug-free communities through public education, professional training and effective tools for those working to prevent drug use and related issues such as violence, teen pregnancy and academic failure. As the Illinois alliance partner for the Partnership for a Drug-Free America, Prevention First has won several national awards for its efforts to educate and inform parents, teens and others about how to prevent youth drug use. Prevention First is the only resource center of its kind in Illinois. Its services include a Student Assistance Center that provides training and support services to schools, particularly in relation to Student Assistance Programs designed to identify those at risk of school failure and intervene to help them succeed. Its Chicago branch office houses an extensive prevention-focused specialized library, while a free Clearinghouse in Springfield distributes nearly 1 million brochures, posters and other materials to schools, youth groups, community organizations, law enforcement agencies and others each year.

Worked examples

Example 1 — a first encounter with Prevention First

Start with the simplest possible case. Write down what Prevention First claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Prevention First before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Prevention First ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Prevention First

In research: Prevention First appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Prevention First in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Prevention First is common in secondary-school and first-year university syllabi. It links to neighbouring topics 501(c)(3) organizations, Drug culture, Non-profit organizations based in Illinois, so understanding it makes those chapters shorter.
In everyday life: Look for Prevention First outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
