If its equiv. to degree? Why should they just put it as degree instead of Adv. Diploma...

The reason is simple... either the module u taking is basic and not reach a limit of degree level or it really meant for Adv Diploma only!!!

Keep in mind... Advance Diploma is TOTALLY Different from Degree!!!
Degree is higher level than Adv. Diploma, if u say d same... den why this Adv. Diploma still exist and claim it as so call or equiv. to Degree Level?!
Thats wat make it a difference that Advance Diploma is TOTALLY Different from Degree!!!
