BSO兼忧虑

收到 college board director 的来信恭喜娃 APCS得了perfect score. 高兴之余更增添忧虑，娃这一枝独秀对上CS到底有多大帮助呢？

"Your performance on the AP Computer Science A Exam in May 2018 was so superior that it falls into a very select category."

"You not only reveived the top score of 5 but were one of only 193 students ( amounting to just 0.295 of 20018 AP Computer Science A Exam takers) from around the world to earn every point possible on this difficult assessment."
