I would like to ask if someone could tell me what I need to do in order to complete CS50 and acquire the certificate. I started the course in 2017, and finished the final assignment some months ago. I believe to have completed all necessary psets to complete the course, but as I haven't receive the certificate from edx to this day, I believe that I am missing something. As CS50 2018 took into account the completed assignments from the course of 2017, I am unable to know what I still have to do. Would you be so kind as to tell me what pset I am missing to finish the course?
Thank you in advance,
