Turn ACT prep books, lecture notes, and practice tests into flashcards, mixed-section quizzes, and full-length practice. Drill English, Math, Reading, and Science — paced to the real ACT timing.
The ACT's biggest weapon isn't difficulty — it's pacing. You get 52 seconds per Science question. Cramberry trains you on real ACT timing, on every section, with material you've already chosen.
English (45 min, 75 q), Math (60 min, 60 q), Reading (35 min, 40 q), Science (35 min, 40 q). Each section has its own pacing puzzle. Cramberry generates timed drills so you build a section-by-section rhythm.
Starting in 2025, the ACT is shorter (~125 questions, ~2 hours core), Science is optional, and the test moved to a mostly digital format. Cramberry handles both the legacy long-form ACT and the new format.
ACT Science isn't a science test — it's a data-reading test. Cramberry generates Science-style passages (data representation, research summaries, conflicting viewpoints) so you stop being surprised on test day.
Unlike the SAT, the ACT doesn't give you a formula sheet. You need to know SOHCAHTOA, log rules, conic equations, sequence formulas — cold. Cramberry's spaced-repetition flashcards lock them in by test day.
ACT English tests about 15 high-frequency grammar rules over and over: comma splices, modifier placement, parallel structure, transitions. Cramberry drills exactly these — not generic English grammar.
When you miss a question, Cramberry's AI tutor walks through the reasoning, suggests a faster approach, and can re-explain it three different ways until it clicks.
Cramberry takes your existing ACT prep material and turns it into a complete study system: section-by-section notes, timed flashcards, mixed-format quizzes, and full-length practice tests.
Upload a prep book chapter, ACT.org practice test, or class handout. Cramberry creates clean study notes organized by section — English grammar rules, Math formula sheets, Reading strategies, Science passage types.
Cramberry's flashcards drill ACT Math formulas (arithmetic through trig), the ~15 grammar rules tested on English, ACT-style vocabulary in context, and Reading-passage genre clues. Spaced repetition shows you the cards you're shakiest on more often.
Generate timed quizzes for any ACT section. English (45 min for 75 questions), Math (60 for 60), Reading (35 for 40), Science (35 for 40). Each question comes with an explanation, and you can ask the AI tutor for a faster approach.
Generate full-length ACT practice tests with all four sections, real timing, and a scaled composite at the end. Use as supplementary practice between your official ACT.org tests.

Cramberry creates notes, flashcards, section-by-section quizzes, and full-length practice tests — all calibrated to ACT timing and difficulty.
Drill with spaced repetition, take timed section quizzes, and ask the AI tutor anything from "why is this answer wrong" to "give me a faster approach."
Most ACT scores plateau around 25–28. The reason: you've absorbed the content but you haven't drilled the specific question types you keep missing. Reading another prep-book chapter doesn't fix this — targeted active recall does.
Cramberry uses spaced repetition to bring back the exact question patterns you keep getting wrong: parallel structure in English, function questions in Reading, conflicting-viewpoints passages in Science. The cards you nail get spaced out; the ones you miss come back tomorrow. Your study minutes flow toward what's actually weak.
Dunlosky et al. (2013) ranked practice testing and distributed practice as the two most effective study techniques across subjects — the exact engines behind Cramberry.
Cramberry doesn't replace your prep books — it turns them into active recall.
