How it works

Each scenario follows the three-step TADA sequence:

1. Step 1 — Benign pattern recognition: Does the lesion show unequivocal features of seborrhoeic keratosis, cherry angioma, or dermatofibroma?
2. Step 2 — Organisation assessment: Is the lesion organised (symmetric, uniform) or disorganised (asymmetric, chaotic)?
3. Step 3 — Feature recognition: Are any of the seven high-risk features present?

You work through each step, check your answer, read the feedback, and then move on. At the end, you see the educational outcome for that scenario along with a key learning point.
