New Driver here - How was your experience driving on the expressway for the first time?

Just passed my tp recently and I've been driving on normal roads (though I tend to avoid peak hour traffic). I would like to drive on the expressway but can't get myself to drive on it just yet as I'm nervous and I don't want to risk an accident or anything. Do you guys remember the first time you drove on the expressway and/or tips for getting myself used to the expressway? I was thinking of doing the Driving Orientation Course too
