- If you finish working your “+” problems and still have time left, you can do either of two
things:
Attempt the “−” problems, but remember not to guess under any circumstance.
Forget the “−” problems and go back over your completed work to be sure you didn’t
make any careless mistakes on the questions you thought were easy to answer.
You do not have to erase the pluses and minuses you made in your question booklet.
The Elimination Strategy
Take advantage of being able to mark in your test booklet. As you go through the “+” ques-
tions, eliminate choices from consideration by marking them out in your question booklet.
Mark with question marks any choices you wish to consider as possible answers. See the fol-
lowing example:A.
?B.
C.
D.
?E.This technique will help you avoid reconsidering those choices that you have already elimi-
nated and will thus save you time. It will also help you narrow down your possible answers.If you are able to eliminate all but two possible answers, answers such as Band Ein the previ-
ous example, you may want to guess. Under these conditions, you stand a better chance of rais-
ing your score by guessing than by leaving the answer sheet blank.Section II: The Free-Response (Essay) Section
Many students waste valuable time by memorizing information that they feel they should know
for the AP chemistry exam. Unlike the history exam, for which you need to have memorized
hundreds of dates, battles, names, and treaties, the AP chemistry exam requires you to have
memorized comparatively little. Rather, it is generally testing whether you can applygiven in-
formation to new situations. You will be frequently asked to explain, compare,and predictin
the essay questions.Section II of the AP chemistry exam comes with- a periodic table (see pages 340 and 341)
- an E°redtable (see page 346)
- a table of equations and constants (see pages 342–345)
