I am confused about the following sentence:
"By the sophomore year, the student should apply for special education services"
Does it mean the students should do it before the 2nd year begins or just after OR it should be done before the end of the 2nd year?
In typical examples, like: "I need to do it by tomorrow" or "By the time we got there, the film had started" it doesn't seem to matter, but what if the period is a year?
EDIT: There's been an error on my part. The original sentence reads:
"By senior year, and/or prior to age 18, apply for..."
though the question remains...
EDIT2: There's actually more examples: See https://books.google.pl/books?id=FS0cAlDkRnEC&printsec=frontcover&hl=pl#v=onepage&q&f=false
pages 30-31.
