Hello. "When I still ..................... school I learned how to make fish paste." I would like to express the idea that the action of going to school was uncompleted. How can I complete the gap? 1. used to go to 2. went to I don't really want to say that I don't go to school now. I'm afraid that #2 can mean a completed action. I don't think I need to use the past continuous here. I think I could use the word attend or be, but I would rather use the word go. Is it possible?
