General ACCAHow should I start for the ACCA qualification?

Hi everybody, I am an Economics graduate with an aim for the ACCA qualification. I need help in choosing an appropriate way to accomplish this. I am exempt from F1- Accountant in Business, I am to start my postgraduate degree on Accounting and Audit in a weeks time. I see that completing the postgraduate degree also earns me exemptions till F-4. So given this situation, should I wait for graduation to register as ACCA student? I am asking to figure out the fast-track route to the ACCA qualification for my case. The thing is that I also registered for the Introduction to Financial and Management Accounting course provided by edX and where the certification is handed after registering with ACCA as a student and completing some related exams. I don't want to study and enter exams with the ACCA where afterwards exemptions will be awarded (completing postgraduate studies) Is this certificate connected with the foundation modules or something independent to the ACCA qualification?
