Slide 1

Welcome to.. THE DAT

Slide 2

What is the DAT? The DAT is the comprehensive test used as a measure of aptitude for entrance into Dental School. *Big factor in admissions/interviews DAT = Dental Admissions Test Cumulative Score of 6 sections for a total of 30 points Scores 0-30 You get three scores: -Academic Average (average of all sections but PAT) -Total Science (average of the three science sections) -PAT (scored individually, not factored into the averages)

Slide 3

National Averages Academic Average ~18-19 The average of students applying is 17. The average of students accepted is a 19-20. To be successful on the DAT, plan to have a BARE MINIMUM of 17 on each section but shoot for a 20 in each section to be safe.

Slide 4

What does the DAT consist of? Biological Science (90 min, 100 MC) -Biology -General Chemistry -Organic Chemistry PAT Perceptual Ability Test (60 min, 90 MC) Reading (60 min, 50 MC)/3 passages ~16-17 questions each QR Quantitative Reasoning (45 min, 40 MC)

Slide 5

Dental Admission Test Actual Layout Optional Tutorial 15 minutes Survey of Natural Sciences 90 minutes Perceptual Ability Test 60 minutes Optional Break 15 minutes Reading Comprehension Test 60 minutes Quantitative Reasoning Test 45 minutes Optional Post Test Survey 15 minutes

Slide 6

When should I take the DAT? The timing of the DAT is very important: OPTIMAL TIME: Summer after you Sophomore year Danger Area: If you have not completely by the end of the summer after your Junior year

Slide 7

Heres the kicker The DAT is completely COMPUTER-BASED. So this means if you are like me and like to read and annotate while you read on the paper, you cant. If you like to mark off answers, you cant. How can I possible overcome this obstacle? Take practice tests. Practice, practice, practice. Scare yourself.

Slide 8

Biology The key to understand with the Biology section is to understand you will NEVER know everything about biology. The biology section is all comprehensive. You could read 30 textbooks and still not know every question. Best resource: Barrons AP Biology Book This resource has tests to quiz you after each section and spells everything out in very plain and simplistic language.

Slide 9

Topics included in Biology: Evolution Genetics Ecology Plants The Cell biochemistry cell respiration Photosynthesis cell division Heredity the molecular basis of inheritance Classification animal physiology the human immune system animal reproduction and development animal behavior

Slide 10

At the end of glycolytic pathway, what is your next production of ATP? 32 ATP 5 ATP 2 ATP 12 ATP No ATP is produced during ATP

Slide 11

Slide 12

What is the main component that fuels the Kreb cycle? Succinyl CoA Acetyl CoA Cholinesterase A-ketogluterase malate

Slide 13

What term represents two or more populations of different species? Ecosystem Community Biosphere Differential Speciation Habitat

Slide 14

_____ provide(s) the major force for the movement of water and solutes from roots to leaves. Translocation Bulk flow Transpiration Root pressure Solute pressure

Slide 15

Reading (60 min, 50 MC) Reading is primarily about your ability to read scientific articles quickly, efficiently and be able to recall information readily Most popular and effective method of attack: -THE ROADMAP You may be thinkingwhat the heck is a ROADMAP?!

Slide 16

ROADMAP A roadmap is a way to catalog information for quick recall. It is a way to annotate a paragraph. Begin by counting the number of paragraphs in an excerpt, and then write down key words or phrases by that paragraphs number as you read, to go back later.

Slide 17

Another challenge (Kaplan wont prepare you for this one) The DAT likes to ask you two part questions in one so sometimes you end up getting double questions. For example, if you read a passage they may pull two ideas out of it and write them out like so. (1) The enamel of your teeth is the hardest surface of the human body (and, or, but) can be eroded by heat, (2) once gone, it is gone forever. The way the DAT would ask the two questions would be: A) Statement (1) is true but statement (2) is false B) Statement (1) is false but statement (2) is true C) Both statements are true

Slide 18

OR it may be a qualifying statement such as: Fiber optic wires are much faster than radio waves because of the insulation. (A) The statement is true but the reasoning is false (B) The statement is false but the reasoning is true (C) Etc. VERY POPULAR!
