This is website of intrax Business English
"Our Professional Certificate in Business & Management is divided into three modules which each last four weeks. You can choose to take only one module (and earn a Single Subject Business Diploma) or take all three one after the other (for a total of 12 weeks) to earn the full PCBM certificate."
So I think they have classes for earning a diploma or certificate.
