Win an advantage when applying for top science universities

More than 10,000 students participate every year in the US

Outstanding students will have the chance to attend top science programs

Date:Sunday 19th April, 2020, 10:00-11:20 am (50 min)


The Center for Excellence in Education (CEE) was founded in 1983. Nurturing careers of excellence and leadership in science and technology in young scholars was an essential investment into America's global future. CEE's programs help keep the US competitive in science and technology, furthering international collaboration among leaders of the world. CEE challenges students and assists them on a long-term basis to become the creators, inventors, scientists, and leaders of the 21st century.

As the premiere biology competition for high school students in the US, the USA Biology Olympiad (USABO) enriches the life science education of nearly 10,000 talented students annually. It provides the motivation, curricular resources, and skills training to take them beyond their classroom experience to a level of international competitiveness.

ASDAN China (ASDAN Academy) and CEE are working together to bringing the USABO Open Exam for the first to China. This exam will be named "BioOlympiad Initiative USA-China" in China. We will be using the same papers and judging standards as USABO to help Chinese students improve their biology skills and understand their level. Outstanding students will have the chance to attend top science programs.Representatives from 163 international and key middle schools have participated in this competition in 2019.

Sample Problems

1. Suppose radioactive thymine was added to an actively dividing culture of E. coli bacteria. What would happen if a cell replicated once in the presence of this radioactive base?

  • Only one daughter cell would have radioactive DNA
  • Neither of the two daughter cells would be radioactive
  • All four DNA bases would be radioactive
  • Radioactive thymine would pair with nonradioactive guanine
  • DNA in both daughter cells would be radioactive

Answer: E

2. If radioactive sulfur (35S) is used in the culture medium of bacteria that harbor bacteriophage viruses, it will later appear in:

  • Bacterial RNA
  • Bacterial cell wallsBacterial cell walls
  • Bacterial cell walls
  • Viral RNA
  • Viral coats

Answer: E

Biology Open Course Ware (Advanced) MIT

OpenCourseWare is a free and open educational resource for educators, students, and self-learners around the world. A student can consult the Introductory Biology courses (7.012, 7.013 and 7.014) and review the associated problem sets. These problems are concept based and excellent way to study once the student has memorized the facts from Campbell’s Biology. The courses may offer actual tapes of the lectures, recitations, notes, readings, problem sets, quizzes and exams. There is no cost.

Biology, An Online Textbook (Less Advanced)

An additional reference for those who wish to check something quickly. It is organized alphabetically, by topic. Rapidly changing topics such as immunology are regularly updated. Many of the graphics are exceptionally well done.
