What are the most frequent tenses in English? A remember when I was a high school student the teacher taught lots of tenses for the class. I always tried to memorise all of the tenses, but it was hard and I thought it wasn't necessary to study all of them. A few years later I started to go a private teacher and she didn't teach me that much tenses, because I don't need to know about 10-12 tenses. What do you think about it? Which are the most important tenses?
