Welcome to….. THE DAT

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)

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.

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)

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

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

Here’s 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 can’t. If you like to mark off answers, you can’t. How can I possible overcome this obstacle? Take practice tests. Practice, practice, practice. Scare yourself.

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: Barron’s AP Biology Book This resource has tests to quiz you after each section and spells everything out in very plain and simplistic language.

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

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

Which organelle has digestive enzymes to break down waste and cellular debris? (a) Golgi apparatus (b) Smooth ER (c) Nucleus (d) mitochondria (e) lysosome lysosome

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

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

_____ provide(s) the major force for the movement of water and solutes from roots to leaves. Translocation Bulk flow Transpiration Root pressure Solute pressure Transpiration, While root pressure is a force involved in the movement of water and solutes from roots to leaves, it is not the primary mechanism by which such movement occurs.

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 thinking…what the heck is a ROADMAP?!

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.

Another challenge (Kaplan won’t 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: Statement (1) is true but statement (2) is false Statement (1) is false but statement (2) is true Both statements are true

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

PERCEPTUAL ABILITY (PAT) 60 minutes 90 questions Subsections: Keyholes, Top-Front-End, Angle Ranking, Hole Punching, Cube Counting, Pattern Folding

Keyholes 10 minutes recommended A 3-Dimensional figure is given, you must determine the best keyhole for which that 3-dimensional object will fit through. 

The Rules The object can pass through the opening in any orientation. The object cannot be rotated once it has started through the opening. The external outline of the object is the exact shape of the opening. The object and opening are drawn to the same scale. There are no irregularities in any hidden part of the object. There is only one correct answer. Strategies Draw projections for back, bottom, and right. Crushing the object

Answers: 6) C 7) C 8) E 9) C 10) C

Front-Top-End 15 minutes recommended You are given two views of a three-dimensional object these views include the front view, the top view, and the end view. You must imagine what the third view is for this object. 

The Rules Strategies Look for changes in angles Presented are top, fron, and end views of various solid objects (there will never be a hollow object with something else hidden) All views are presented without perspective The top, front, and end views are always presented in the same position relative to a cross (grid). Edges of the object that cannot be seen are represented by DOTTED lines Strategies Look for changes in angles Ask if you can see edges from where you’re standing Fold the quadrants

Answers: 6) D 7) C 8) A

Angle-Ranking 5 minutes recommended You must determine the relative sizes of the interior angles of the four figures from smallest to largest.

-smallest and largest angles THE RULES Four interior angles are given and must be ranked in order of increasing size. Strategies -smallest and largest angles

Hole Punching 5 minutes recommended A square sheet of paper is folded, then hole(s) are punched in that folded sheet of paper. Mentally unfold the paper and determine were that square paper has hole punches from choices A-E.

The Rules Strategies -lines of symmetry -number of folds A flat, square piece of paper is folded one or more times. Broken lines indicate the original position of the paper, and solid lines indicate the position of the folded paper. The folded paper remains within the boundaries of the original, flat sheet. The paper is not turned or twisted. There are one, two, or three folds per question. Strategies -lines of symmetry -number of folds -layers of paper

Answers: 6) B 7) B 8) C

Cube Counting 10 minutes Each figure has been created by cementing cubes together of the same size. The cubes are then painted except for the bottom face of all the cubes. Determine the number of sides painted for each cube. 

The Rules Strategies Six types of cubes Tallying the cubes: columns, entire figure Each figure has constructed by cementing together identical cubes After being cemented, each figure was painted on all sides EXCEPT for the bottom (pretend it’s sitting on a table) The only hidden cubes are the ones necessary to support other cubes in the figure

4) How many cubes have 2 sides painted?

Answers: 4) 6 5) 2 6) 6

Pattern Folding 15 minutes recommended

The Rules Strategies Unique face of the pattern Unique shading A flat pattern is presented at left There is only one correct 3-D figure for each question The flat pattern represents the OUTSIDE of the figure (fold the pattern into the page). Strategies Unique face of the pattern Unique shading Focus on Key Landmarks
