As per my knowledge they should be in some alignment, meaning for example someone has done B.Sc Food Science and is working as a manger at some clothing store, he cannot then claim points for his B.Sc. In that way, I meant that the points you claim for education should be in alignment with your work, otherwise you will only be eligible for points in either one of them not both.
P.S- I do not claim to be a expert, just someone who has researched, I could be wrong. i ask other members also to express their views in this regard, so that no misleading information is passed on. It is most important that correct information is spread.
