Praxis Core Cheat Sheet.
The night-before summary, built like the exam.

The three subtests

• Reading (5713): 85 min · 56 questions · all selected-response on passages/statements
• Writing (5723): 100 min = 40-min 40-question selected-response + two 30-min essays
• Mathematics (5733): 90 min · 56 questions · selected-response + numeric entry
• Combined = 5752, all three in one session, $150 · at home or test center · 4 free score recipients
• Passing scores are set by each state — check yours first; unscored pretest items are unmarked, so answer everything

Reading anchors

• Every answer is in the passage — outside-knowledge choices are traps by design
• Main idea / best title must span the WHOLE passage, not one detail
• Inference = the most modest conclusion the text supports; beware always/never/entirely
• Vocabulary in context: substitute each choice into the sentence
• Fact vs opinion = verifiable vs evaluative · transition words reveal structure (however = pivot, indeed = intensifier, first/next = sequence)
• Weakening a causal claim = find the alternative explanation or exposed assumption

Writing anchors

• SR section parts: usage · sentence correction · revision-in-context · research skills
• Subject-verb: ignore the prepositional phrase — each/every = singular; neither…nor = agree with the nearer subject
• Opening participle must modify the main-clause subject (dangling modifier)
• Series must stay parallel in tense and form · 'only' modifies what it touches
• Comma alone between independent clauses = splice; semicolon or comma + conjunction joins legally
• Case: object of preposition = me ('between you and me'); who/whoever by role inside its own clause
• Plural possessive: coaches' · affect = verb, effect = noun · hardly/scarcely already negative
• Essays (30 min each): arguable thesis + one-job paragraphs + specific support; plan 5 / write 20 / revise 5

Math anchors

• Areas: Number & Quantity · Data/Stats/Probability · Algebra & Geometry
• PEMDAS: exponents before multiply before add · signed substitution in parentheses
• Percent change base = the earlier value · sale price ≠ discount amount
• Median needs sorted data · mean × count = total (work backward for missing values)
• Probability = favorable/total · NOT-event = 1 − P · area = l×w, perimeter = 2(l+w) · triangle angles sum 180°
• Slope = Δy/Δx · 'seven less than twice n' = 2n − 7 (English order reverses)
• Numeric entry has no choices: estimate first, then compute

Night before

• Re-run the grammar rules and math formula rows above — they are the whole selected-response game
• Confirm your state's cut scores and your named score recipients
• At-home testers: system check, quiet room, webcam ready
