Final answer:
The information provided does not specify whether Henrietta and Day finished school or what grade they completed.
Step-by-step explanation:
From Dr. Edward's notes, it is mentioned that at the end of the six-year course in 1908, he won the George Brown Scholarship, which is the highest honor available in the course. This suggests that Dr. Edward completed his education.
In the case of the other individuals mentioned, such as Henrietta, Day, Henry, and John, there is no specific information provided about their completion of school or the grade they completed.
Therefore, based on the given information, it is unclear whether Henrietta and Day finished school or what grade they completed.
