What's the equivalent today?

A couple thoughts that come to mind:

• One must use quill and ink vs pen. You don't want to lose your quill skills.
• One must not use a dictionary. You need to build those phonics skills.

In my personal experience restrictions on how one takes a test, is a sign that the person who wrote the test does not want to spend the time and effort developing good question.
