下面是英文的介绍：

They are all titles for a Masters degree. MSc is for Master of Science, MLitt is for Master of Literature and MA is for Master of Arts.

MLitt is usually used for arts degrees and so it is similar to MA. Most universities use MA but some (usually older universities) like to use MLitt. But it makes no difference to your qualification.

Business is one of the few subjects where degrees can be called a Master of Science or a Master of Arts. So you might see degrees at different universities called, MSc Management, MA Management, MLitt Management. The only important thing here is that the MSc Management is probably a more mathematical course than the MA Management or MLitt Management.
