Going back to the OP, I saw that your stated religion is Anglo-Catholic. I think this thread has turned toward an assumption that you were unfamiliar with the EF of the Mass. Now I’m leaning towards thinking that you are really asking about the New order of the Mass.(guessing here!) That is actually easier since there is more availability to attend an Ordinary Form, or New Order Mass. There are usually more Mass times available on Sunday, as well as on Saturday evening. So, it would be possible to check out a Mass on Sat night, and then attend your usual Mass on Sunday, if that is something that you were looking to do.
If you are simply looking for differences, you could still very well find a wealth of information on this site, YouTube, and Googling in general.
In short: There are things permitted in the new Mass that are not in the EF, such as Communion in the hand, female altar servers and lecturers, as well as Eucharistic Ministers (I believe there is another name for them, but it escapes me right now). And, as someone already stated, the liturgical calendar is different. There are also some slight differences in vestments. In the OF, the congregation will offer a sign of peace to each other with handshakes, which is not done in the EF. (I’m assuming that is still done…?) I think that is about it for the major things that will be most evidently different between the two forms.
Hope that helps!
