The Strange Dual Nature of the SAT II
The official name of the SAT II Biology is actually the
SAT II Biology E/M. The test has this strange name because it’s
actually two tests built into one. One test, the Biology E Test, emphasizes
ecology and evolution. The other test, the Biology M Test, emphasizes
molecular biology and evolution. On test day, you will take either
the Biology E or the Biology M test. You can’t take both.
The Biology E and Biology M Tests aren’t completely dissimilar.
In fact, out of a total of 80 questions, the two tests share a core
of the same 60 questions. The test contains an additional 40 questions,
split between the E and M specialty sections. So if you take the
Biology E test, you will only have to answer the section of 20 ecology
and evolution questions. If you take the Biology M, you need only
answer the molecular biology and evolution section.
