Outline of the AP Biology Exam:

- 100 multiple choice in 80 minutes= 60% of test
- 4 Free Response Essay Questions in 90 minutes (10 minutes reading time)= 40% of test

Essay Section Hints:

-The 4 essay questios are graded equally.
One question is on molecules and cells.
One question is on genetics and evolution.
Two questions are on organisms and populations.

-One or more of the questions will be lab-based. (PLEASE SEE LAB SECTION GUIDE BELOW!)

-Write in essay form! There is room on the test for you to create an outline to guide your answer if you'd like but outlines are not graded. That being said, perfect essay writing is not expected. There aren't deductions for grammer or spelling mishaps (provided the spelling is close enough to determine the word you are trying to write).

-Diagrams are helpful! If you use a diagram, be sure to refer to it in your essay.

-Points are not deducted from your essay score if you give an incorrect statement. (You just don't receive points for incorrect statements). But be careful not to contradict yourself

LAB ESSAY QUESTIONS     Lab Essay Questions will often present an experiment setup very similiar to one of the AP labs you performed. In EVERY Lab Essay Question, you should discuss the following information even if the question does not specifically ask for it:   (remember, you are never deducted for too much information, but keep it relevant): -State the hypothesis and identify it as such -State the control group -State the dependent and independent variable(s) -Identify other variables being held constant (i.e. amount of time, stirring, etc...typically there are two of these) -Identify what you are measuring (ex. pressure, change in mass) -State how and when data will be collected (ex. meausure mass after 30 minutes) -State what calculation will be used (ex.avg 3 values for mass) -State how you will be confident in your results (ex. repeat trials) -State how you will share your results (ex. tables, graphs) -State what you expect to happen and why Plants that feed on other organisms often do so b/c of very little nitrogen to uptake (poor soil).
