Can I take notes during a mass?

I was raised roman catholic for the first 13 years of my life. The rest I spent agnostic of religion after I read the bible. Books like Leviticus made me very upset. Now I heard that this doesn't actually get preached in most churches, and a lot of people call themselves Christian because they believe in certain values rather than believing the bible word for word. I'm very interested in getting to know how much of what actually gets preached matches with things I believe in. I want to figure that out by going to a couple of masses. From my religious youth I have learned that everyone is welcome in a church, but a lot of things are considered rude, like wearing a hat as a male or not standing or kneeling at the appropriate times (if you're able to). Now my question is, is it considered impolite or rude in any way if I take notes during preaching? The goal of the notes is being able to study the preaching afterward. Is there any Catholic teaching that would make this wrong or improper?
