<p>There are two different biology tests. Both test contain the same first 60 questions. Later, additional 20 questions come from your choice of subject (either E or M)</p>
<p>I suggest you take a look at Sparknotes below:
[SparkNotes:</a> SAT Subject Test: Biology: Introduction to the SAT II Biology](<a href=“http://www.sparknotes.com/testprep/books/sat2/biology/chapter2.rhtml]SparkNotes:”>http://www.sparknotes.com/testprep/books/sat2/biology/chapter2.rhtml)</p>
<p>If you want to score really high, I suggest getting Barron’s SAT II Biology book or PR.</p>
