第一集
「有教無類」這句治學名言在斗南中學校長孔令陽心目中是完全不存在的，對他來說，教育絕對有分類！
斗南中學中每個年級都依智力和考試成績區分成A至Ｆ六個班級，被分類到A班的學生自然是倍受呵護的天之驕子，朝會有特別座位，教學設備特別齊全，至於F班的學生，套句孔校長常說的話：「學校的電費總是要有人來贊助嘛！」。
在A 班眾天之驕子中， 又以IQ200又十項全能的天才學生江直樹最受人矚目，更是孔校長深以為傲的斗南之光。
然而，在凡事少根筋的袁湘琴眼中「愛是沒有等級的」。自從二年多前，新生入學那天聽到江直樹代表新生致詞，湘琴便深深喜歡上聰明沉穩的直樹，雖然在斗南中學中，A班和F班的學生之間的差距就像隔了一彎深深的太平洋，但樂觀的湘琴還是勇敢地向直樹表白，結果，可想而知，湘琴果然被直樹狠狠拒絕了，更成為全校的笑柄。羞憤的湘琴終於認清了「夢想」與「現實」的差距，決定放棄這長達兩年多的暗戀。
