You have finished semester 1 of Anatomy and Physiology! Way to go! I hope you and your family have a wonderful break and stay healthy. All of your positive attitudes and commitments to working hard inspired and motivated me this semester. Thanks for all the effort and time you put into this class, and for being such great individuals!! Looking forward to semester 2 full of new turns and adventures. Together, we've got this!
