While peer reviewing a certification video in Biology, I saw that when the individual clicked the link to open the Khan Academy test for the Chemistry of Life unit, the link instead took the user to the unit page (https://www.khanacademy.org/science/ap-biology/chemistry-of-life) rather than the unit test page (https://www.khanacademy.org/science/ap-biology/chemistry-of-life/nucleic-acids-ap/test/chemistry-of-life-unit-test). The user then had to manually scroll through the page to find the link to begin the unit test.
