Laura finds herself falling deeply for Almanzo in spite of the considerable age gap between them. She is also sick and tired of being thought of as a "little girl" and thinks of a sure fire way to be considered more 'grown up' - she wants to take the graduation exam like Nellie and then the teaching exam so that she will be qualified to teach.
The problems begin when she asks Nellie for her help. We know immediately that things are not going to turn out well as Nellie seems practically incapable of doing or saying anything nice at any time. Laura should have known better but that would have made the episode far less interesting and it was certainly a terrific one for the second part of the season opener. You will definitely have to watch this one as well as the one before it. Terrific!
