Taking classes through Coursera or EdX

hello, I recently discovered I can take a 15wk biochem course on EdX through Harvard university online. I thought of using this as satisfying my biochem prereq for med schools but I don’t know if they even accept this. I get a certificate verifying I completed the course and passed it with 70 or higher. can i use it to satisfy the prereq needed? it was very affordable too? just thought id the question here.
