这个“油膜”不去除，严重的话，在雨天、雪天、雾天，前风挡即使有雨刮不断刮也会视线模糊，危险性极高。 I'm trying to locate the most standard expression or phrase for the opposite of "online course". When a program isn't online, but in a classroom, or any where else persons interact in the exact same area, not by means of a computer, how would I call it?
