# Out-of-Sample Submission Selection

During the Out-of-Sample, your code will be run every week on a submission of your choice.

{% hint style="info" %}
By default the system selects the best successful run.
{% endhint %}

**If and only if** you want to select another submission than the best run, use the Out-of-Sample Parameters Selector.
