Who won the gold medal? Why wasn't Gilbert going on to Redmond inthe fall?

Anne won the medal.

"Three cheers for Miss Shirley, winner of the Avery!"

"Oh, Anne," gasped Jane, as they fled to the girls' dressing room amid hearty cheers. "Oh, Anne I'm so proud! Isn't it splendid?"

Gilbert isn't going to Redmond because he can't afford the tuition.

"Gilbert Blythe is going to teach, too. He has to. His father can't afford to send him to college next year, after all, so he means to earn his own way through. I expect he'll get the school here if Miss Ames decides to leave."
