Is there any Russification of the Simple MCQ Drupal 7 module?
It looks like it is partially translated: Translate Simple MCQ to Russian.

To import the translation that exists into your own site, enable the core Locale module and add Localization update.  You can now use the standard Drupal translation site interface to translate the bits that are not translated.

Please help the community by adding your own translations to Localize.Drupal.org
