2 Multiple Choice: New format (2004)- 100 questions in 80 minutes 25% molecules and cells 25% heredity and evolution 50% organisms and populations ¼ point guessing penalty no longer used

3 Time is critical!!!!! answer all questions on first attempt- skip if you dont know use left over time for skipped questions first answers normally correct study all diagrams carefully look for odd man out answer

4 Essay Exam 4 questions 1 molecules & cells 1 heredity & evolution 1 organisms & populations one essay based on a lab

5 New for 2004 10 minute reading period outline answers book opened after 90 minutes for writing

6 Scoring- the readers gain points for correct statements no deduction for wrong answers can abbreviate use sentences- NOT outline NO 5 paragraph format! drawing permitted- must be explained- only part of credit

7 Writing tips!!!! read question carefully outline then write give details and specific examples If question in parts, write answer in parts (Label!) underline key words or phrases equal amounts of time on each question

8 dont refer to another question NEVER leave essay question blank! no money in pages dont assume reader will know what you mean give definition to all terms use the whole page (and more) watch handwriting and use ink use English

9 Test day tips!!! get plenty of sleep take caffeine stimulant if necessary to get going in morning arrange for sugar drink during break between two parts

10 Things to remember!!! You have trained all year- if you have prepared, you should do well each essay point counts more- attempt to earn as many as possible
