I'm wondering about using the word "I" in the expository essay. I have always been taught to never use the word "I" in almost any essay. It feels odd to me to write along the lines of "I think block scheduling should be instituted in all high schools because... " instead of something like "Block scheduling is the best choice for high schools because..." Can anyone give me some feedback here? It seems the scorers are expecting the word "I" to be used, so I should just do it. Thanks.
