# How often the question library gets refreshed?

Xobin's question library is refreshed every **3 to 6 months** to ensure a high-quality, relevant, and up-to-date assessment experience. 

Here's how we manage it:
* **New questions are added** regularly to prevent repetition and keep assessments fresh.
* **Outdated or irrelevant questions are removed** to ensure candidates are never presented with unsuitable content.
* **Retention decisions are based on success rates** — frequently used and well-performing questions are retained, while questions that are rarely used, irrelevant, or unsuitable for candidates are removed.
This ongoing process ensures that every assessment on the platform remains accurate, effective, and reflective of current industry standards.
