備考指南

Preparation Advising

01、從(cong) BBO備賽，進階USABO

From BBO to USABO

盡管同為(wei) 生物奧賽選拔賽，BBO與(yu) USABO相比更易入手，原因主要有三點：

在題量上，USABO初賽50分鍾需要做完50道題，平均1分鍾1道，而BBO90分鍾完成65-80道題，出題會(hui) 根據難度調整題數。因此，USABO相較於(yu) BBO更具挑戰力，更適合學霸。
在詞匯上，USABO的競賽詞匯不僅(jin) 涉及生物類學術詞匯，同時還會(hui) 涉及大量美國本土學生熟悉、但對國際生、新移民比較陌生的生活類詞匯，比如說曼陀羅花、馬蹄蟹等。對於(yu) 生物知識掌握比較到位、但英語還未完全同步的學生來說，BBO更為(wei) 友好，更容易出成績。
在獲獎概率上，BBO最高獎項每年約有500個(ge) 名額，而USABO則隻有50個(ge) 名額，當然如果在兩(liang) 項賽事中均能獲獎多多益善，但從(cong) 概率的角度上來說，BBO獲得成就感的機會(hui) 還是更多一些的。

所以說，建議各位學霸們(men) （尤其是低年級學生）可以從(cong) BBO入手開始鞏固生物知識點、鍛煉考感，可能會(hui) 在來年的USABO中取得更好的成績。

Students are encouraged to start preparing for BBO and then USABO as BBO is relatively less challenging than USABO.

USABO Open Exam requires a completion of 50 problems in 50 minutes while BBO requires a completion of 65-80 problems in 90 minutes and adjusts the difficult level according to the number of total problems.
USABO covers more biology and academic vocabulary.
BBO offers about 500 first-prize awards while USABO offers about 50.
