Kindly please if i am planning to study marketing diploma, which one i should go for AUC or Eslsca?

Th AUC programme looks much better. AUC also has the three most respected international accreditations (eslsca has none) and the AUC diploma also includes the Chartered Institute of Marketing certificate.

AUC is for most people the better choice. Is this the diploma that you're looking at?
