Ultimate Digital SAT Cram Sheet

This is your last-minute battle plan for the Digital SAT. Since the transition to the digital format, the rules have changed. This guide focuses strictly on the adaptive nature of the test, the built-in Desmos calculator usage, and the highest-yield content you need to secure your score.

1. Exam Overview & Format

The Digital SAT is computer-adaptive. This means how you perform on the first module of a section determines the difficulty of the second module. You generally want to get to the "Hard" second module to unlock the highest score potential.

SectionModulesQuestionsTimeTime Per QuestionContent
Reading & Writing (RW)254 (27/module)64 min (32/module)~1.19 minLiterature, History, Science, Grammar, Rhetoric
Math244 (22/module)70 min (35/module)~1.59 minAlgebra, Advanced Math, Problem Solving, Geometry
Total4982 hrs 14 min--

CRITICAL: There is a 10-minute break between the Reading & Writing section and the Math section. Use it to reset your brain.

Tools & Policies

  • Calculator: Desmos is built into the testing app (Bluebook) and is available for ALL math questions. You can also bring your own approved handheld calculator.
  • Annotation: You can highlight text and add notes within the app.
  • Timer: A countdown timer is visible at the top of the screen (you can hide it until the last 5 minutes).

2. Scoring & What You Need

  • Total Score: 400–1600
  • Section Scores: 200–800 for RW; 200–800 for Math.
  • Guessing Policy: NO PENALTY for incorrect answers. Never leave a bubble blank. If you run out of time, pick a "Letter of the Day" and fill it in for remaining questions.
  • The Adaptive "Floor": If you perform poorly on Module 1, you get an easier Module 2, but your maximum possible score is capped (usually around 600-650 per section). You must prioritize accuracy in Module 1 to access the 700+ range.

3. Section-by-Section Strategy

Reading & Writing (RW)

Distinct from the old SAT, passages are short (25–150 words) with only one question per passage.

  1. Group by Type: You can answer questions in any order within a module. Use the "Mark for Review" tool.
    • Strategy: Do Standard English Conventions (Grammar) and Words in Context first. They are fast and objective.
    • Save Inferences and Command of Evidence for last as they require heavy reading.
  2. Vocabulary Strategy: If you don't know a word, identify the "charge" (positive/negative) of the sentence. eliminate options with the wrong tone.
  3. Command of Evidence: Read the hypothesis or claim in the prompt first. You are looking for the answer choice that directly supports or undermines that specific claim. Ignore interesting but irrelevant facts.

Math

  1. Desmos is King: You can solve roughly 30-40% of questions just by typing equations into the graphing calculator.
    • System of equations? Graph them and find the intersection.
    • Find the equivalent expression? Graph the question and the answer choices. If the lines overlap perfectly, it's a match.
  2. Student-Produced Responses (Grid-ins): You can enter negative numbers, decimals, or fractions. If an answer is a repeating decimal, fill the entire box (e.g., enter .6666 or 2/3, not just .6).
  3. Drawing Not to Scale: Unlike the old SAT, figures in the digital SAT are generally NOT drawn to scale unless explicitly stated. Do not estimate lengths by eye; calculate them.
  4. Plug in Answer Choices: If the algebra is tricky, plug the multiple-choice options back into the problem (Start with answer B or C to gauge if you need to go higher or lower).

4. Highest-Yield Content Review

Math: The "Must-Know" Formulas & Hacks

The Digital SAT provides a reference sheet (Area/Volume), but you need to memorize these:

ConceptFormula / RuleDesmos Tip
Slope-Intercepty = mx + b (m=slope, b=y-intercept)Type directly to visualize slope
Vertex Formy = a(x-h)^2 + k (Vertex is at (h, k))Type to find max/min height
Quadratic Formulax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}Or just graph and look for x-intercepts
Discriminantb^2 - 4ac
>0: 2 real solutions
=0: 1 real solution
<0: 0 real solutions
-
Sum of Solutions-b/a for ax^2+bx+c=0Faster than solving!
Product of Solutionsc/a for ax^2+bx+c=0Faster than solving!
Circle Equation(x-h)^2 + (y-k)^2 = r^2
Center: (h,k), Radius: r
Graph it to find points/transform
Exponential Growth/Decayy = a(1 \pm r)^t
a=initial, r=rate (decimal), t=time
-
SOH CAH TOA\sin(\theta) = \frac{Opp}{Hyp}, \cos(\theta) = \frac{Adj}{Hyp}, \tan(\theta) = \frac{Opp}{Adj}Type "sin(x)" in Desmos (Check Degrees vs Radians)
Probability\frac{\text{Target Outcomes}}{\text{Total Outcomes}}Watch for "Given that…" (reduces denominator)

Reading & Writing: Grammar "Cheat Sheet"

  • Semicolon (;) = Period (.) = Comma + FANBOYS.
    • If you see answer choices where the only difference is a semicolon vs. a period, both are likely wrong.
    • Semicolons separate two independent clauses (full sentences).
  • Colon (:)
    • Must have a full independent clause before the colon.
    • What comes after can be a list, a sentence, or a single word explaining the first part.
  • Dash (—)
    • Single dash: Acts like a colon.
    • Double dash: Acts like parentheses (removable information).
  • Subject-Verb Agreement
    • Ignore prepositional phrases between subject and verb.
    • Example: "The box [of old toys and dusty books] is heavy." (Box is singular, use is).
  • Dangling Modifiers
    • The introductory phrase must describe the subject immediately following the comma.
    • Wrong: "Walking down the street, the trees looked beautiful." (Trees can't walk).
    • Right: "Walking down the street, I thought the trees looked beautiful."
  • Transitions
    • Continuers: Furthermore, Moreover, Additionally, Indeed (Logic: A, and also A).
    • Contrasters: However, Nevertheless, Conversely, Despite this (Logic: A, but B).
    • Cause/Effect: Therefore, Thus, Consequently, As a result (Logic: Because A, then B).

5. Common Pitfalls & Traps

  1. Solving for x instead of 2x

    • The Trap: You do all the algebra to find x=5, but the question asks for the value of 2x + 1. Option A will inevitably be 5.
    • The Fix: Circle what the question is asking for before you start solving. Reread the last sentence before picking your answer.
  2. Unit Conversion Blindness

    • The Trap: The question gives rate in miles per hour but asks for distance traveled in minutes.
    • The Fix: bold or highlight units. If inputs and outputs don't match, multiply/divide by 60.
  3. The "Absolute" Trap (Reading)

    • The Trap: Choosing answers with words like "always," "never," "everyone," or "totally proofs."
    • The Fix: SAT correct answers are usually nuanced. Look for softer language like "suggests," "may," "often," or "some."
  4. Misidentifying the Subject

    • The Trap: Confusing the subject with the object of a preposition.
    • The Fix: Mentally cross out any text starting with "of," "in," "on," "with," or "between" to find the true subject.
  5. Percent Change Direction

    • The Trap: Thinking that increasing by 20% and then decreasing by 20% gets you back to the start.
    • The Fix: 100 \times 1.2 = 120. 120 \times 0.8 = 96. You do not end up at 100. Always run the numbers.
  6. Desmos settings

    • The Trap: Using radians mode for a degree problem.
    • The Fix: Click the wrench icon in Desmos. Ensure you are in "Degrees" for triangle problems unless \pi is involved.

8. Last-Minute Tips & Test Day Checklist

The Night Before

  • CHARGE YOUR DEVICE: This is non-negotiable. Bring your power cord, but arrive at the center with 100% battery.
  • Updates: Open the Bluebook App one last time to ensure no auto-updates are pending.
  • Download: Ensure your exam setup is complete and your admission ticket is generated in the app.
  • Sleep: Do not do practice problems after 8 PM. Your brain needs to consolidate memory.

Test Day Checklist

  • [ ] Testing Device (fully charged laptop/tablet).
  • [ ] Power Cord/Charger (portable chargers are allowed).
  • [ ] Admission Ticket (digital or printed).
  • [ ] Photo ID (physical, acceptable ID).
  • [ ] Pencils/Pens (for scratch work on provided paper).
  • [ ] Snack & Water (for the 10-minute break—sugar helps focus).
  • [ ] A Watch (optional, silent—though the app has a timer).

Mental Strategy

  • Don't Panic on Hard Questions: If Module 2 feels incredibly hard, take it as a compliment—it means you crushed Module 1.
  • Reset: If you bomb a reading passage, close your eyes for 3 seconds, breathe, and treat the next question as a fresh start.

You have prepared for this. Trust your strategies, trust Desmos, and go get that score.
