什么是ACSL?

ACSL全称American Computer Science League美国计算机科学联盟 (ACSL) ,为 K-12 学校和团体组织计算机编程和计算机科学竞赛。 ACSL连续运营已接近50年了!去年,美国、加拿大、欧洲和亚洲的 700 多支队伍参加了比赛。 参加每场比赛的学生人数不限。每个赛季分为四场比赛,测试学生计算机科学的基本概念,从Number Systems到Boolean Algebra再到Digital Electronics。在高等组别中,每场比赛还包括一个使用 Python、C++ 或 Java 编程解决的问题。 比赛以在线形式进行,优秀的学生将被邀请参加全美在线总决赛。

ACSL 分为五个等级:Senior, Intermediate, Junior, Classroom, and Elementary,为不同年龄和能力的学生提供适当的挑战。各个部门的竞赛主题相似,但在详细度和难度方面有所不同。在一个等级内,一所学校组成一个或多个Team。每个Team最多可有 12 名学生。一名学生只能作为一个Team的成员参加, 不能同时参加多个Team。

以下是五个等级的介绍:

  • Senior Division:适合有编程经验的高中生,尤其是那些修读 AP 计算机科学的高中生。比赛包括30 分钟的 5 道简答题和72 小时内解决的在线编程问题。
  • Intermediate Division: 适合编程经验很少或没有编程经验的初高中生。比赛包括30 分钟的 5 道简答题和72 小时内解决的在线编程问题。
  • Junior Division (9年級以下): 适合正在学习编程或有编码经验的6~9年级学生。比赛包括30 分钟的 5 道简答题和72 小时内解决的在线编程问题。
  • Classroom Division: 向所有年级的学生开放。适合参加 AP 计算机科学原理和其他没有编程的计算机科学课程的学生。每场比赛都包括在线的 50 分钟、10 个问题的简短回答测试。没有编程问题。
  • Elementary Division(3 - 6 年级): 每场比赛都包含30 分钟的 5 题非编程测。每场比赛将测试不同的类别,此等级没有编程问题。 ​

常见问答:

1. 考试形式

各个级别都有四次考试,每个月一次,從1月份開始,考试的形式是在线,在HackerRank上进行。

2. 如何參加总决赛? 根据常规赛成绩,将邀请各赛区优秀学员参加线上总决赛: 每年 5 月 1 日至 5 月 16 日发出電子郵件邀请參加當月進行的决赛
