there is Aiken format in Moodle. (Many formats are available but Aiken is easy)
Link for you reference: https://docs.moodle.org/36/en/Aiken_format
You can create questions, options in that format and import them directly.
Remember these questions will directly be imported in the question bank.
From the Question bank, you can use for any quiz. You can export these question bank category and reuse for another course or in next year.
You can also use Moodle2Word plugin for uploading questions via word files. However, this requires you to install plugin on your Moodle as well as local MS Word. You can refer http://www.moodle2word.net/ for more details on this. We will cover plugin installation and settings in later tutorials.
