Summarize Scout's assessment of second grade.
Scout is, in a word, disappointed.
She is an intelligent little girl who seems to be ahead of most of her peers. She can already read and write, but instead of having a teacher who recognizes this as a positive quality, Miss Caroline tells Scout she is wrong for learning outside of school and thus invalidates any knowledge she has that Miss Caroline has not given her. This all happens on the first day of school, so Scout cannot help but be disappointed at having to put up with an entire year of performing below her actual skill levels.
In addition, Miss Caroline seems generally irritated by Scout's perceived meddling, as Scout jumps into the conversation about Walter Cunningham and tries to explain why he does not have any lunch and will not be able to accept her offer of lunch money. Altogether, Scout really "gets off on the wrong foot" on her first day of second grade!
Sadly, Scout's experiences at Maycomb's local elementary school did not hold fond memories. After a terrible first day of first grade, things never got much better. Apparently, the same can be said of her second year of grade school.
The second grade was as bad as the first, only worse--they still flashed cards at you and wouldn't let you read or write.
Things continued as usual with Miss Caroline next door, judging by the "frequency of laughter" heard through the walls.
The second grade was grim, but Jem assured me that the older I got the better school would be...
Scout decided that the only good thing about second grade was that she got out of school the same time as Jem, and they walked home together each day at 3 p.m.
