USABO SEMIFINAL WORKED SOLUTIONS

[Biology Olympiads Study group]

Dear all,

Hope everyone is preparing hard for the upcoming USABO 2021 semifinals. As probably many of you, we have noticed that some past papers have mistakes in the answer keys. Thus, we have published a bunch of worked solutions with our proposed answers of all available USABO semifinals except for the 2017 paper (which we are working on at the moment).

These solutions contain valuable insight on how to approach difficult questions. They will walk you through the most efficient methods which can help you rapidly get the correct answer. Filled with examples of time saving techniques and score boosting strategies, this is a must-buy for anyone using past papers as part of their USABO preparation.

Check them out at https://biolympiads.com/shop/. 

Keep up the hard work! 

Best wishes,

Martyna
