Congratulations on making to the final assessment module of this course! The exam will focus on the new module materials from this course: the endocrine system, blood and lymphatic systems, cardiovascular system, and respiratory system. However, you still have to know all the basic rules, roots, prefixes, and suffixes from the beginning of the specialization since they apply to these systems as well. Learning a language is cumulative like that! I'm confident you've got this. So breathe and believe...
