EJU Syllabus for Biology (To be applied to the questions of the 2015 EJU 1st Session (June))

[Purpose of the Examination]
The purpose of this examination is to test whether international students have the basic academic ability in science necessary for studying at universities or other such higher educational institutions in Japan.
[Classification of Examination]
The examination consists of three subjects, i.e. physics, chemistry, and biology; examinees will select two of these subjects.
[Scope of Questions]
The scope of questions is as follows. What is taught in elementary and junior high schools is regarded to have been already learned and therefore is to be included in the scope of the EJU. What questions consists of in each subject is classified into categories, each of which is presented by topics and scientific terms.


The scope of questions will follow the scope of “Basic Biology ” and “Advanced Biology” of the curriculum guidelines for high schools in Japan.
