<p>^Yes, as zach447 stated, the essay questions are what usually includes the AP labs. On the labs, its important to know WHY the results are the way they...are, and clearly know the controls and variables for each. Cliff's covers this area extremely well, and I think that's how it earns its great reputation. Not to mention that its very detailed in other info as well. </p>
<p>On the essay questions don't freak out when you read some of those that they have included in the book. Those, IMO look like they were written by some professor. When they are grading your essays the scorers go and look for facts you have mentioned, not how good your transistions are, your grammer, etc. They look for key points that they want you to mention about a topic. Still, not a bad idea to read over all those essays, and learn how you can include knowledge to the essay questions you will get on your exam.</p>
<p>"Molecular and Ecology" I was asking myself the same question my sophomore year, and the reason that I went with molecular first is because I MYSELF was more comfortable with the material. </p>
<p>Are you more knowledgeble with things such as:
Mendel's theories, Hybrids/X-Breeding, Polymorphism, Mitosis/Meiosis, Cellular level processes, metabolism, protein/RNA translation/transcription, and cell organaization + DNA and structures of microorganisms? Go with Molecular.</p>
<p>Are you more knowledgeble with things such as:</p>
<p>Evolution, Population growth, limiting factors, organism relationships, environmental, and behaviors? Go with Ecology.</p>
<p>Don't forget about the regular portion of the test, the E or M portion is the last couple questions. The majority is plain old biology, plant/animal structures, natural selection, organ systems, hormones, etc. </p>
<p>If you're not exactly sure WHAT your strengths are, take some sample tests and grade yourself. See which are you're a bit fuzzy on, and if those questions fall more into the M section, then maybe you're better of with E for now. Use those practice tests to not only plainly practice, but to discover what areas your strengths are.</p>
<p>If you happen to find out that your strengths are about the same for both areas, ask your teacher, or even, look how your book is structured. Does the last material that you cover end up as Ecology? Then that will be most fresh on your mind when you take the exam. If all else fails and you still can't decide, flip a coin. After all, its the majority of the regular bio questions you should worry about if you're comfortable with both E and M.</p>
