No. There’s no timer, and each question uses a 4-option multiple-choice format.

Can I choose the number of questions I answer?

Yes. You can select your preferred question count before starting, from shorter practice runs to longer sessions.

What difficulty should I pick if I’m new to the topic?

Start with an easier setting or a shorter set, then move to Mixed once you’re comfortable with basic terms like MO and signature.

What’s the most common mistake people make here?

Confusing modus operandi with signature behavior is the top pitfall, especially when two cases share similar methods.

About this quiz

What you’ll practice

This quiz focuses on distinguishing “signature” behaviors from modus operandi, and linking recurring patterns to specific cases without relying on vague stereotypes.

You’ll also sharpen case-reading skills: picking out the one detail that matters among similar-sounding scenarios.

Format and difficulty controls

Each question has 4 options and there’s no timer, so you can slow down and reason through the evidence.

Choose your preferred question count and difficulty before you start: shorter sets are great for quick revision, while longer runs build pattern recognition; mixed difficulty blends easier identifiers with tougher, easily-confused comparisons.

Common pitfalls to avoid

Many players mix up signature vs. MO, or assume every repeated behavior is a “calling card.” Another frequent mistake is over-weighting sensational details instead of consistent victimology, geography, and routine.

Tips for better scores

Separate what helps the offender succeed (MO) from what gratifies them (signature)
Watch for victim type, approach method, and disposal patterns as a combined profile
Don’t anchor on one dramatic clue; confirm with at least two supporting details
Be cautious with similar cases that share era/location—read every qualifier
Use the no-timer format to eliminate options systematically, not instinctively

How the balance works

Difficulty is balanced by mixing straightforward pattern matches with higher-challenge items that test nuance, overlap, and exceptions—so you’ll get momentum early and still face meaningful stretch questions later.
