<p>Most books have this. It is a DIAGNOSTIC test that should be the very first one you take to see where you stand. It has more questions and (if I am correct) a different score conversion chart included… they do this to more accurately evaluate your starting abilities and show you what topics you are getting wrong (there should be a chart that says "questions 1-15 are ____ topic and questions 16-30 are ____ [ecology or biochem are examples])… </p>
<p>Haha this is coming from someone who has taken plenty of biology subject tests</p>
