Part 1: Mental Ability

• Verbal Reasoning: Involves analogies (e.g., $Microscope:Lens::Telescope:Objective$), word classifications, and identifying antonyms (e.g., $Meticulous$ vs. $Careless$; $Ephemeral$ vs. $Permanent$).
• Non-Verbal Reasoning: Focuses on identifying patterns through text descriptions, including:
  • Increments in dot count (e.g., $1, 2, 3, 4$ dots in varying patterns).
  • Rotation (e.g., right triangle rotating $90^{\circ}$ clockwise).
  • Color spectrum sequences (Red, Orange, Yellow, Green, then Blue).
  • Geometric progression (doubling counts at each level).
• Logical Reasoning:
  • Syllogisms: Deductive conclusions based on standard premises (e.g., "All mammals are vertebrates; All vertebrates have backbones; Therefore, all mammals have backbones").
  • Conditional Logic ($P \rightarrow Q$): Differentiating between valid deductions (Modus Ponens/Modus Tollens) and fallacies (Affirming the Consequent).

Part 2: English Proficiency

• Grammar and Usage:
  • Subject-Verb Agreement: Use singular verbs for collective nouns like "Committee" ($has reached$) and distributive pronouns like "Each" ($is responsible$).
  • Parallelism: Corresponding lists must maintain consistent forms (e.g., "increasing, improving, and enhancing").
  • Modifiers: Avoiding dangling modifiers by ensuring the introductory phrase modifies the correct subject.
• Vocabulary:
  • Erudite: Scholarly and learned.
  • Caustic: Sarcastic or biting remarks.
  • Ephemeral: Temporary or fleeting.
  • Auspicious: Suggesting a positive outcome or favorable.
• Literature and Rhetoric:
  • Literary Devices: Simile (comparison using "as"), Hyperbole (exaggeration), Antithesis (parallelism of opposites like "best of times, worst of times"), and Verisimilitude (appearance of truth).
  • Themes: Noli Me Tangere by Jos Rizal focuses on Spanish colonial oppression and social reform.
• Reading Comprehension Themes:
  • Photosynthesis: Essential for regulating Earth's climate; approximately $70\%$ of atmospheric oxygen originates from aquatic phytoplankton.
  • Carbon Sequestration: Mature forests can absorb $2.4\,tons$ of $CO_2$ annually.
  • Language Evolution: Human linguistic capacity is linked to specialized brain structures (Broca's area, Wernicke's area) and a lower larynx; written language emerged approximately $5,000$ years ago.

Part 3: Mathematics

• Algebra:
  • Quadratic Equations: Solving forms like $2x^2 - 7x + 3 = 0$ using factoring or the quadratic formula.
  • Systems of Equations: Solving for two variables using substitution or elimination.
  • Simplification: Factoring binomials and trinomials (e.g., $x^2 - 4 = (x-2)(x+2)$).
  • Sequences: Arithmetic ($a_n = a_1 + (n-1)d$) and Geometric ($a_n = a_1 \times r^{n-1}$).
• Geometry:
  • Pythagorean Theorem: $a^2 + b^2 = c^2$; applied to ladders leaning against walls.
  • Circle Properties: Area ($A = \pi \times r^2$) and Circumference ($C = 2 \times \pi \times r$).
  • Volume: For cylinders, use $V = \pi \times r^2 \times h$.
• Trigonometry:
  • Sine, Cosine, Tangent: Know values for $30^{\circ}$, $45^{\circ}$, and $60^{\circ}$ (e.g., $\sin(30) = \frac{1}{2}$, $\tan(45) = 1$).
  • Identity: $\sin^2(\theta) + \cos^2(\theta) = 1$.
  • Laws: Law of Sines ($\frac{a}{\sin(A)} = \frac{b}{\sin(B)}$) and Law of Cosines ($c^2 = a^2 + b^2 - 2ab \times \cos(C)$).

Part 4: Science

• Biology:
  • Classification: Specific order is Kingdom, Phylum, Class, Order, Family, Genus, Species; Human scientific name is Homo sapiens.
  • Circulatory System: Flow follows $RA \rightarrow RV \rightarrow Lungs \rightarrow LA \rightarrow LV \rightarrow Body$.
  • Cell Biology: Mitochondria produce $ATP$; Lysosomes handle waste; DNA replication occurs in the S-phase.
  • Genetics: Heterozygous crosses ($Tt \times Tt$) yield a $3:1$ phenotypic ratio ($25\%$ recessive offspring).
• Chemistry:
  • Periodic Trends: Atomic radius increases down a group; Electronegativity (highest in Fluorine) increases across a period.
  • Stoichiometry: Molar mass of $H_2SO_4$ is $98\,g/mol$.
  • Acids and Bases: $pH = -\log[H^+]$; a solution with $[H^+] = 10^{-3}\,M$ has a $pH$ of $3$.
• Physics:
  • Newton's Second Law: $F = m \times a$.
  • Energy: Kinetic Energy ($KE = \frac{1}{2}m \times v^2$); Potential Energy ($PE = m \times g \times h$).
  • Constants: Speed of light in a vacuum is approximately $3 \times 10^8\,m/s$.
  • Electricity: Coulomb's Law ($F = k \times \frac{q_1 \times q_2}{r^2}$).
• Earth Science:
  • Geology: Rock cycle (Igneous, Sedimentary, Metamorphic); Limestone metamorphoses into marble.
  • Plates: Convergent boundaries form trenches and volcanic arcs; divergent boundaries form new crust.
  • Atmosphere: The ozone layer is found in the stratosphere.
