1 Facts About the AP Biology Exam

2 Structure of Test / 3 Hours long / Divided into two sections / Section I multiple choice questions / Section II--4 Essay questions / 3 Hours long / Divided into two sections / Section I multiple choice questions / Section II--4 Essay questions

3 Section I / 100 multiple choice questions / 45 seconds per question / 80 minutes to answer 100 questions / 3 parts / Regular multiple choice questions / Matching questions / Questions dealing with experiments or data / 100 multiple choice questions / 45 seconds per question / 80 minutes to answer 100 questions / 3 parts / Regular multiple choice questions / Matching questions / Questions dealing with experiments or data

4 Section II / 4 Essay questions / 10 minute reading period / 90 minutes to answer all 4 essays / 22 minutes per essay / 4 Essay questions / 10 minute reading period / 90 minutes to answer all 4 essays / 22 minutes per essay

5 Section I--- / 58 multiple choice questions / Example: If a segment of DNA reads 5- ATG-CCA-GCT-3, the mRNA strand that results will be (A) 3-TAC-GGT-CGA-5 (B) 3-UAC-AGT-CAA-5 (C) 3-TAA-GCU-CGA-5 (D) 3-UAC-GCU-CGA-5 / 58 multiple choice questions / Example: If a segment of DNA reads 5- ATG-CCA-GCT-3, the mRNA strand that results will be (A) 3-TAC-GGT-CGA-5 (B) 3-UAC-AGT-CAA-5 (C) 3-TAA-GCU-CGA-5 (D) 3-UAC-GCU-CGA-5

6 Section I-- / Experiments or data / Given a diagram and multiple choice questions about diagram / Common sense/ logical deduction more useful than strict science / Experiments or data / Given a diagram and multiple choice questions about diagram / Common sense/ logical deduction more useful than strict science

7 Section II / 4 free response essays / Divided into parts--vary in difficulty / Questions / Area 1: Molecules and cells / Area 2: Heredity and Evolution / Area 3: Organisms and populations / 4 free response essays / Divided into parts--vary in difficulty / Questions / Area 1: Molecules and cells / Area 2: Heredity and Evolution / Area 3: Organisms and populations

8 Sample Free Response / Enzymes are biological catalysts / A. Relate the chemical structure of an enzyme to its catalytic activity and specificity / B. Design an experiment that investigates the influence of temperature, substrate concentration, or pH on the activity of an enzyme / C. Describe what information concerning enzyme structure could be inferred from the experiment you have designed / Enzymes are biological catalysts / A.

9 Scoring / Maximum points Section I-100 pts / 60% of grade / Maximum points Section II- 40 pts / 10 pts per essay question / 40% of grade / Raw scores translated into composite scores---then to AP number grade 1-5 / Maximum points Section I-100 pts / 60% of grade / Maximum points Section II- 40 pts / 10 pts per essay question / 40% of grade / Raw scores translated into composite scores---then to AP number grade 1-5

10 Example / (Raw score for section I)=(Number answered correctly)-(Number wrong÷4) / Convert raw score to composite score / (Composite score of section I=0.75x(Raw score for Section I) / (Raw score for section II)=(Points for essay 1)+(Points for essay 2)+(Points for essay 3)+(Points for essay 4) / (Composite score for section II)=1.5 x(Raw score for section II) / (Raw score for section I)=(Number answered correctly)-(Number wrong÷4) / Convert raw score to composite score / (Composite score of section I=0.75x(Raw score for Section I) / (Raw score for section II)=(Points for essay 1)+(Points for essay 2)+(Points for essay 3)+(Points for essay 4) / (Composite score for section II)=1.5 x(Raw score for section II)

11 ETS Grading System Composite score AP GradeComment Extremely well qualified Well Qualified Qualified Possibly Qualified No recommendation

12 Strategy 1: Pace Yourself! / Take your time--do not need to answer every question--mistakes accounted for / Go for questions you know skip the ones you dont / Take your time--do not need to answer every question--mistakes accounted for / Go for questions you know skip the ones you dont To get scoreSection ISection II 1252 to 3 essays 2403 essays 3603 to 4 essays 4854 essays essays

13 Strategy 2: Three-Pass System / Perfect score- do not have to answer every question / Skip most difficult questions / Easiest questions first / Medium questions second pass / Hard question last pass / WATCH THE BUBBLES! / Perfect score- do not have to answer every question / Skip most difficult questions / Easiest questions first / Medium questions second pass / Hard question last pass / WATCH THE BUBBLES!

14 Strategy 3: Process of Elimination (POE) / The structure that act as the sites of gas exchange in a woody stem are the (A) Lungs (B) Gills (C) Lenticels (D) Ganglia (E) Lentil beans / The structure that act as the sites of gas exchange in a woody stem are the (A) Lungs (B) Gills (C) Lenticels (D) Ganglia (E) Lentil beans

15 Strategy 4: Aggressive Guessing / 4 wrong answers = Loss of 1 point / Eliminate 2 answer choices--guess / 4 wrong answers = Loss of 1 point / Eliminate 2 answer choices--guess

16 Strategy 5: Word Associations / Know your science vocabulary / Help you to narrow down choices / Know your science vocabulary / Help you to narrow down choices

17 Strategy 6: Mnemonics / King Phillip of German came over for great spagetti / Kingdom, phylum, class, order, family, genus, species / King Phillip of German came over for great spagetti / Kingdom, phylum, class, order, family, genus, species

18 Strategy 7: EXCEPT questions / 10 percent -Except/Not/Least / Wrong--Least correct / Cross of the ones that apply to question / 10 percent -Except/Not/Least / Wrong--Least correct / Cross of the ones that apply to question

19 Strategy 8: ETS Essay / ETS readers looking for hot button terms= points / Read each question 2x / 10 minute period- brainstorm write down key terms / Outline essay using key terms / If asks for 2 examples--give just 2 examples / Use diagrams but must label correctly / ETS readers looking for hot button terms= points / Read each question 2x / 10 minute period- brainstorm write down key terms / Outline essay using key terms / If asks for 2 examples--give just 2 examples / Use diagrams but must label correctly

20 Signal Words / Description- detailed verbal picturejust the facts--not opinions / Discussion-conversation among ideas / Explain-take something complicated and make it more clear--simpler terms / Compare- answer that is focused on similarities between 2 things / Contrast- answer emphasizing differences / Description- detailed verbal picturejust the facts--not opinions / Discussion-conversation among ideas / Explain-take something complicated and make it more clear--simpler terms / Compare- answer that is focused on similarities between 2 things / Contrast- answer emphasizing differences
