I am an international applicant who have been waitlisted by PSE for APE M1 programme. I really want to be got an offer for this programme so I would like to increase my chance if possible. I have already sent an e-mail to ask my ranking in the waitlist, but they didn't reply. What should I do to increase my chances of getting off the waitlist? Do you think it is okay to send an e-mail to coordinator and explain my strong interest? I would be really grateful if those have any experience with PSE or waitlists answer my question.
