• You should get your license.
• You ought to get your license.

The difference is that “ought” is seen as a formal word choice and is therefore used less frequently than “should,” which is informal. If you’re writing a formal piece, use the word ”ought.” But if you’re just speaking to a friend, “should” is fine to use.
