Should 'is or was' be used here? High school student as he is/was, his speech yesterday was superior to a college student's. In my humble opinion, 'is' should be used in the subordinate clause because it is ture that he is a high school student. However, 'was' is also used by some people in this situation. Is the purpose to keep the verb tense agreement between the subordinate clause and the main clause? Thank you!He is a high school student which is true.('True was misspelled as 'ture' in my question.) Is or was should be filled in the blank of the following sentence? High school student as he_____, his speech yesterday was superior to a college student's.
