Biology Practice Questions Feedback

After completing some biology practice questions in Macromolecules, I noticed the same questions being repeated. For example, the nucleic acids and proteins practice sections have the exact same questions as the nucleic acids and proteins quiz and unit test. I understand that this is very good, quality content, but this repetitiveness makes me question the usefulness of having so many practice sections that are all the same. I assume this is also the case with the other biology subsections; adding more practice questions would be amazing.
