https://www.coursera.org/courses?languages=en&query=public+health Courses from top universities with certificate. Nominally a $49 fee per course but one can apply for financial aid if self-described in need. I've had three courses fee-waived. I was disappointed in the first course I completed "An Introduction to Population Health" from Manchester University. I thought the course was simplistic and biased. I'll report on how my other courses go.
