The
SAT II
Biology covers the biology topics taught in any standardAmerican high school biology course, with particular emphasis on eitherecology or molecular biology. ETS breaks the test down into five basiccategories:
| Topic | Number of Questions |
| Cellular and Molecular Biology | 8–11 |
| Ecology | 8–11 |
| Classical Genetics | 7–9 |
| Organismal Biology | 22–26 |
| Evolution and Diversity | 7–10 |
As we said, depending on which specialtysection you elect to take, you will also face 20 questions (25 percentof the total questions you will see) in either ecology/evolution ormolecular biology/evolution.
While these categories are helpful, they arealso very broad. For example, you may have cell structure down pat, butbiochemistry throws you for a loop, and you would like to get a senseof how much of the test is devoted to these two topics. To help youout, we’ve broken the core of the test down even further, so thatyou’ll know exactly where to expect to feel the squeeze.
| Topic | Number of Questions |
| Cellular and Molecular Biology | 8–12 |
| The Cell and Cell Structure | 4–6 |
| Biochemistry and Organic Chemistry | 3–5 |
| Cell Processes | 1–3 |
| Mendelian and Molecular Genetics | 8–10 |
| Evolution and Diversity | 8–10 |
| Evolution | 2–4 |
| Diversity | 4–6 |
| Organismal Biology | 20–26 |
| Animal Structure, Function, and Behavior | 9–13 |
| Plant Structure and Function | 9–13 |
| Ecology | 7–9 |
This book is organized according to thesecategories, allowing you to focus on each topic to whatever de
gree youfeel necessary. Also, each question in the practice tests at the backof this book has been sorted into these categories, so that when youstudy your practice tests, you can very precisely identify yourweaknesses and use this book to address them.
