Clicking it opens a small form where you choose one of: * **No formula** — Chamilo's normal scoring (default) * **Recalculate question scores** — Redistributes option weighting without a penalty * **Successes − Failures** * **Successes − Failures / 2** * **Successes − Failures / 3** The chosen formula applies only to that specific test. > This setting does not change the question or answer weights themselves — it changes how the final score is computed. If the plugin is disabled, or no formula is selected, Chamilo falls back to its original scoring. ## Tips * **Test on a copy first** — Changing a formula can change the scores students end up with on that test; try it on a duplicate test before applying it to a live one * **Explain the change to students** — A penalty formula can be surprising if learners are used to simple correct-answer scoring; mention it in your instructions
