No need to apologize. We're all stressing out to enter dental school
I'm taking the the US DAT..so I'm not too sure if the Canadian DAT is the same or similar? but anyways, I'm pasting an outline for what the US DAT is composed of. If you feel like you know the material, just peruse each topic and just go over what you think are your weak spots. I can't tell you how long the studying will take...maybe a month or so but everyone is different.
DAT:
Biology (40)
Cell and Molecular Biology - origin of life, cell metabolism (including photosynthesis/
enzymology, cellular processes, thermodynamics, organelle structure and function,
mitosis/meiosis, cell structure, and experimental cell biology
Diversity of Life: Biological Organization and Relationship of Major Taxa (Six-Kingdom,
Three-Domain System) – plantae, animalia, protista, fungi, eubacteria (bacteria), archae,
etc.

immunological, digestive, respiratory, urinary, nervous/senses, endocrine, reproductive,
etc.
Developmental Biology - fertilization, descriptive embryology, developmental
mechanisms, and experimental embryology

cladistics, population and community ecology, ecosystems, and animal behavior
(including social behavior).
General Chemistry (30)
Stoichiometry and General Concepts - percent composition, empirical formulae,
balancing equations, moles and molecular formulas, molar mass, density, and
calculations from balanced equations
Gases - kinetic molecular theory of gases, Dalton's, Boyle's, Charles's, and ideal gas law

Organic Chemistry (30)
Mechanisms: Energetics, and Structure - elimination, addition, free radical, substitution
mechanisms, and other
Chemical and Physical Properties of Molecules - spectroscopy (1H NMR, 13C NMR, infrared, and multi-spectra), structure (polarity, intermolecular forces (solubility,
melting/boiling point, etc.), and laboratory theory and techniques (i.e. TLC, separations,
etc.)
Stereochemistry (structure evaluation) - chirality, isomer relationships, and conformations
Nomenclature - IUPAC rules and functional groups in molecules
Individual Reactions of the Major Functional Groups and Combinations of Reactions to
Synthesize Compounds - alkene/alkyne, aromatic, substitution/elimination, aldehyde/
ketone, carboxylic acids and derivatives, and other For each area listed above, the
following sub-areas apply: general, one-step, and multi-step.
Acid-Base Chemistry - ranking acidity/basicity (structure analysis and pH/pKa data
analysis), and prediction of products and equilibria
Aromatics and Bonding - concept of aromaticity, resonance, atomic/molecular orbitals,
hybridization, and bond angles/lengths.
The Perceptual Ability Test is comprised of six subtests: 1.) apertures, 2.) view
recognition, 3.) angle discrimination, 4.) paper folding, 5.) cube counting, and 6.) 3D form
development.
Reading Comprehension (50)
The Reading Comprehension Test contains three reading passages on various scientific
topics. Prior understanding of the science topics is not a prerequisite to answering the
test items. The reading passages require the ability to read, comprehend, and analyze
thoroughly basic scientific information.
Quantitative Reasoning (40)
A basic four function calculator is available on the computer screen in this section only;
see image below. The calculator is operated using the mouse, not the numerical keypad.
Mathematical Problems - Algebra (equations and expressions, inequalities, exponential
notation, absolute value, ratios and proportions, and graphical analysis); Numeric
calculations (fractions and decimals, percentages, approximations, and scientific
notation); Conversions (temperature, time, weight, and distance); Probability and
Statistics; Geometry; and Trigonometry
