This course provided a very good amount of information to use when applying for jobs in the public health sector and a certificate to show qualification. Unfortunately, this course implements a peer graded assignment twice. The fist assignment is straight forward and hard not to pass, but the second has a lot to do with the grader's comprehensibility. For example, if the curriculum is to contain the word "dose" in your explanation and you provide "the amount of a chemical used" then you could or will receive no credit for a well thought out paragraph. It is because of this I rated this course.

The topics are covered in great detail. Many lectures, at least to me, seem a bit repetitive in defining key terms over and over again. Also the presentation (slides only) seems a little uninspired. At the end you are mostly presented with rather long videos. Yet it is high quality content.

tem ótimos tópicos abordados, e reflexivos. no entanto achei ele ligeiramente extenso poderia ser mais resumo, uma vez que este seja um pouco repetitivo de mais.
