Computer Science


A student in Ms. Grace's USACO Bronze class for the 2017 fall semester got a 1000 for the Bronze contest in December and proceeded to pass to Silver then qualified for Gold. Many of Grace's students qualified silver.

Several Mr. Qin's students received great result for USACO diferent levels and reached to platinum level. Some of them had been admitted into many top colleges like MIT, Stanford, UC Berkely etc.

USACO Class Prerequisite

Bronze requirements: Understanding of basic Java. Can write code without syntax errors, and knows basics such as arrays, loops, conditionals.

Silver requirements: Fluency in Java or C++. Ability to consistently solve Bronze problems. You should be very familiar with conditional statements (if/else), loops (for/while), arrays, and strings. Knowledge in classes, object-oriented programming, comparators, iterators, etc. is preferred.

Gold requirements: Ability to consistently solve silver problems. The Gold material assumes knowledge of Silver class material, such as knowing how to do BFS, DFS, and sorting, as well as know how to use standard data structures like arraylists, linked lists, stacks, queues, deques, heaps (priority queues), and binary search trees (TreeMap/map, TreeSet/set).

Platinum Requirements: Already qualified USACO Platinum level.

*We offer one trial class (the first class of each course), and if you are not satisfied after the first class, you may cancel and are not required to pay tuition for it.

* Check payable to SpringLight,   mail or drop to the office at 20432 Silverado Ave. Suite 7, San Jose CA 95014 , or  PayPal to We will charge 3% extra if PayPal charges us. Payment need to be received before the 2nd class. Late payment will have $50 penalty.
*Students who miss a class can make it up by watching videos of the class and coming to the teacher with any questions.
*All tuition fees are for group classes with more than four students


 Mr. Qin has more than 3 years teaching experience for programming, AP CS and all level of USACO and more than 8 years programming contest experience. All of his students at SpringLight got level promotion. Several of them got perfect score to silver, gold and/or platinum levels. He will not only systematically teach the algorithm and other concepts used in USACO, but also problem solving skills with logic thinking.
秦老师有着丰富的programming,AP CS 和USACO计算机奥赛的教学经验,并取得了显著的教学成果:去年夏天开始跟秦老师从USACO最初级铜级(Bronze)在USACO竞赛中取得了最高级白金级(Platinum)。而且不少同学满分晋级银级Silver和金级Gold和白金级Platinum,以及正在努力finalist。秦老师将他丰富的教学及竞赛经验结合生动的例子整理出了一堂堂干货”满满的系统性教学来帮助学生夯实基础,详解算法,解题技巧,逻辑思考,开拓思路。
