Course is well organized and very good presented. You can feel the pre-work behind. Lecturers take their job very seriously. Examinations and peer review assignments lead to review what you've learnt and better understanding. Thanks to all efforts.

That was an interesting coursework. The lectures were taught to the understanding of all.

Nice understanding and structured course. It has strongly deepened my knowledge on health outcomes of chemicals.

Very Good Introduction to Environmental Chemical Exposure
