Exam Blueprint

Two Sections · 60 MC + 7 FRQs

🧮

MC No Calculator

Section I (No Calculator)
35%90 min~45 questions
  • › Tests conceptual understanding — no calculator means chemistry REASONING, not arithmetic
  • › Multi-select questions (choose 2) are highest risk/reward
  • › Periodic table and formula sheet provided

Score 5 Tip: The no-calculator MC is won by understanding trends and patterns: electronegativity, atomic radius, ionization energy, polarity, solubility rules. Memorize the periodic table trends cold.

✏️

MC Multi-select + Grid-in

Section I (Multi-select)
15%90 min (shared)~15 questions
  • › Multi-select: must choose EXACTLY 2 correct answers — no partial credit
  • › Grid-in: calculate a numerical answer with the periodic table
  • › Often tests stoichiometry, solution concentration, and equilibrium

Score 5 Tip: On multi-select: answer the question independently, then match to choices. Don't let two similar-looking answers confuse you — re-read both carefully.

📝

Long Free Response

Section II · Long FRQ
30%105 min (shared)3 FRQs
  • › FRQ 1: Experimental design or multi-part reaction analysis
  • › FRQ 2: Equilibrium, kinetics, or thermodynamics with calculations
  • › FRQ 3: Structure/bonding with explanations (IMF, polarity, properties)

Score 5 Tip: In AP Chem long FRQs, SHOW ALL WORK. If you set up the equation correctly but make an arithmetic error, you may still earn most points. Never skip steps.

⚗️

Short Free Response

Section II · Short FRQ
20%105 min (shared)4 FRQs
  • › 4 short FRQs testing: net ionic equations, Lewis structures, predict products, explain observations
  • › Each is 4 points — answer EVERY part even if uncertain
  • › Precision matters: 'hydrogen bonding' not just 'attraction between molecules'

Score 5 Tip: Predict products FRQs: check solubility rules, identify acid-base or redox reaction type, write the net ionic equation. Practice writing NIEs for all strong acid + base combinations.

🧪~14% of total score
Long FRQ · Task 1

Experimental Design/Multi-part Reaction

~35 min

Multi-part question on experimental design or a complex reaction analysis. Often involves interpreting lab data, identifying sources of error, and proposing improvements.

Scoring Criteria
· Experimental design: valid procedure with controls
· Data interpretation: connecting observations to chemical principles
· Calculations: correct setup and units throughout
· Error analysis: identifying and explaining potential sources of error
Score 5 Strategy
Read ALL parts before starting — later parts often clarify earlier ones
For experimental design: state what you measure, what you vary, what you hold constant
Always specify units in every calculation — lost points on units is avoidable
Show the full setup even if you think you'll make an arithmetic error
For error analysis: think about systematic vs. random errors and direction of effect
Reference lab techniques by name: titration, calorimetry, spectroscopy
Model Opener

To determine the rate constant k, I would measure the initial concentration of reactant A using a spectrophotometer (Beer's Law: A = εlc) at t = 0, then record absorbance at regular time intervals to track concentration change.

📊~14% of total score
Long FRQ · Task 2

Quantitative Analysis

~35 min

Multi-part FRQ requiring calculations with equilibrium, kinetics, or thermodynamics. Expect ICE tables, Gibbs free energy, cell potentials, or rate law determination.

Scoring Criteria
· Correct identification of relevant equation or law
· Proper setup of the calculation with labeled variables
· Accurate arithmetic (partial credit available for correct setup)
· Correct answer with proper significant figures and units
Score 5 Strategy
Write the relevant equation FIRST before plugging in numbers
Label every quantity with its symbol and unit
For ICE tables: always check that equilibrium concentrations are positive
For ΔG: confirm sign matches spontaneity prediction (ΔG < 0 = spontaneous)
Check significant figures — AP Chem typically expects 3 sig figs
If stuck, write what you know — partial credit is awarded for correct reasoning
Model Opener

Given: Kc = 4.2 × 10⁻³ at 400°C. Setting up the ICE table with initial concentrations of [A] = 0.500 M and [B] = 0.300 M, and letting x = change at equilibrium: ...

Long FRQ · Task 3

Structure/Bonding/Properties

~35 min

Asks you to connect molecular structure, bonding type, and IMFs to observed physical or chemical properties. Lewis structures, VSEPR, and IMF reasoning are central.

Scoring Criteria
· Lewis structure: correct connectivity, lone pairs, and formal charges
· Geometry: correct VSEPR name and bond angles
· IMF identification: correct type with justification
· Property explanation: logically connecting structure to macroscopic behavior
Score 5 Strategy
Draw Lewis structures carefully — wrong structure = lost points on all parts that follow
Always name the geometry AND the electron geometry if both are asked
IMF questions: identify the strongest IMF present, then explain its effect on properties
For polarity: check geometry AND bond polarity — a symmetric molecule can be nonpolar
Practice IMF ranking in order: LDF < dipole-dipole < H-bonding < ionic/ion-dipole
Use precise language: 'hydrogen bonding between the O-H bond and lone pair on N'
Model Opener

The Lewis structure of PF₃ shows phosphorus with one lone pair and three P-F bonds. Using VSEPR, the electron geometry is tetrahedral and the molecular geometry is trigonal pyramidal with bond angles slightly less than 109.5°.

⚗️~7% each of total score
Short FRQ × 4

Predict/Explain Short FRQs

~70 min total (4 × ~17 min)

Four focused short-answer questions testing: predict products, write net ionic equations, draw Lewis structures, or explain a chemical observation with precise reasoning.

Scoring Criteria
· Predict products: correct formula, state, and charge
· NIE: correct ions, balanced charge, correct states
· Explanation: correct principle cited with direction of effect
· Precision: chemical terminology used correctly
Score 5 Strategy
Predict products: identify reaction type (precipitation, acid-base, redox) FIRST
For precipitation: check solubility rules — memorize the exceptions (NO₃⁻, NH₄⁺ always soluble)
Acid-base reactions: strong acid + strong base → salt + water; identify conjugates
For 'explain' questions: state the principle, then apply it to this specific situation
Net ionic equations: cancel spectator ions; confirm charges balance on each side
Don't over-explain — short FRQs reward concise, precise answers over lengthy ones
Model Opener

When Na₂SO₄(aq) is added to Ba(NO₃)₂(aq), a white precipitate of BaSO₄ forms. Net ionic equation: Ba²⁺(aq) + SO₄²⁻(aq) → BaSO₄(s). BaSO₄ is insoluble per solubility rules, so Ba²⁺ and SO₄²⁻ are the only participating ions.
