USACO Silver

Year Round Part I

Silver level is the first serious step of USACO competition. One must master a variety of algorithms to be able to pass this level. This is why Star League Silver curriculum is twofold: Foundations courses (Part I and Part II) and Problem Solving. Foundations courses teaches the necessary algorithms. Part I is the first in the series.

The class starts by introducing the concept of efficiency and frequently used Data Structures. See the curriculum tab below for other covered topics.

The class is language agnostic. Instructors use pseudo language when necessary to explain programming concepts. However, they are able to help both Java and C++ users when they need help. They also present necessary syntax and language constructs in Both Java and C++ when necessary.

One need not pass the Bronze contest in order to take this course. However, student must have completed Bronze training (Bronze Part I, II, and PS) to take this class by having solved all of the exercises and problems in the Bronze courses.

Each class features lecture teaching the topic of the day and several past USACO problems or related exercise questions. After the presentation of a problem instructor demonstrates how to identify the need to use the content of the day's lecture and steers the students towards an acceptable solution through critical questions and hints. At the end the instructor wraps up the discussion and provides a clear solution that demonstrates the usefulness of the day's topic. Students are expected to implement their solution or the presented solution as homework until next meeting.

During the optional office hours students get individual help about challenging concepts they encounter during their study of the course material.

The student must have finished Bronze training (Bronze Part I, II, and PS) or past the Bronze contest. AP Computer Science A course is equivalent to Part I and Part II. If a student consistently can fully solve at least two problems at any Bronze contest they can start Silver training with this course and keep practicing for Bronze contest.

You can either take a published contest at the official USACO website ( or take our Placement test here. First you will need to create an account for the student for the respective site. Please contact us if you encounter any difficulty.

Year-round classes are recommended for younger students. Year-round (YR) classes cover entire curriculum during the live discussion of weekly meetings. In contrast, in the Intensive (INT) version of the same course, selected portions of the curriculum are provided as recorded lectures in order to cover twice as much material in a week. Office hours are integral part of the Intensive classes. They are optional for the year-round classes. Year-round classes finish the level curriculum in two parts, where Part I is taken in the Fall and Part II is taken in the spring. However, Intensive courses finish the level curriculum in one semester.

If you need to take an Intensive course that is not available, you may want to take a self paced version bundled with live office hour.
