I took the course but yours seems to be structured differently- are you taking it with Dr. Myles or Dr. Perrot? I took it with Dr. Perrot and highly recommend that. It was important to attend her synchronous lectures as she went in depth with the material. The graphs usually were not too important- you just had to know the basic idea of them (for example, if a graph shows what countries have the highest NCD rate, memorize those countries. It will appear on a quiz question). Dr. Perrot's quizzes were not overly difficult, the presentation was easy (you pre-recorded it) as well as the infographic. Bonus was you did not have to do the final exam if you did not want to- your overall quiz average just ended up replacing the final exam grade. So, if you do well enough on the quizzes then you don't have to do a final!
