翰林國際學術活動流程
Euclid比賽規則

1. 比賽時長共2.5個小時，150分鐘
2. Euclid共有10道題，無選擇題，均為簡答題，每題都有2-3小題
3. 一些題目只需寫出最后的答案，一些題目需要寫出計算過程，一些題目需要寫出完整證明過程。評分標準不光是以最終結果正確與否給分，也會根據答題步驟及思路和技巧來給分。如果答題步驟或方式過為散亂，即使最終結果是正確的也不會給予滿分。
4. 可使用計算器，且大部分計算器均可使用，但還有以下功能的除外
（網絡功能，與其他設備溝通功能，存儲功能，電腦代數系統，動態幾何軟件）

Euclid備賽

University of Waterloo滑鐵盧大學官方建議為：

1. Grade 12 open courseware：

這是一個Center for Education in Mathematics and Computing（CEMC）開設的網課，有數學和計算機的課程。滑鐵盧大學推薦參賽者上Advanced Functions and Pre-Calculus（高端方程與預備微積分）和Calculus and Vectors（微積分與向量）兩門課程

2. Mathematics Resource Manual for High School Students and Undergraduate Studies：

這本書盤點了高中數學的主要內容，不僅能成為準備學術活動的利器，也能幫助同學們由高中更好地進入大學數學的學習

3. Euclid eWorkshop：

這是CEMC為Euclid打造的準備材料，類似于一個帶有例題的概念表，盤點了參加Euclid Contest所需要的知識點

4. 往屆比賽題目：

往屆比賽題目是很珍貴的準備學術活動的資源，做這些題目不僅能幫助參賽者復習知識點，也能讓他們更加熟悉Euclid的出題方式和套路，更好地應對比賽
