That's not correct actually. She is talking about pronunciation. The classical pronunciation is just that- pronunciation. MP uses ecclesiastical(church latin) pronunciation only (CAP includes both, you choose what you want to use) . One example of the difference is that in classical latin the v is pronounced w. (So sal-ve is pronounced sal-we in the classical pronunciation). Both programs present latin grammar and expect you to know what the counterpart is in english grammar. What is an adjective for example? You need english grammar alongside both. We use CAP, because in highschool my children learn classical latin. I don't want them to have to try and switch pronunciation when they get there.
