How Crambly works

In short (updated 2026-11-05): Upload your class files; Crambly sorts them, maps every topic and how your professor tests it, forecasts your next quiz or exam, and runs practice sessions on your weakest, most-tested topics.

Three steps take you from a pile of PDFs to knowing what's on the test.

1. Upload your class

Add your syllabus, lecture slides, notes, study guides, homework and past quizzes. Crambly reads PDFs, Word, PowerPoint, Excel, photos of handwritten or graded work, whole folders and .zip packs, then sorts everything into folders. If it's unsure what a file is, it asks you.

2. Crambly maps how your professor tests

Crambly builds a map of the course: every topic, what each one builds on, where it shows up in your materials, and the aspects of it a question can test. It studies past quizzes to learn your professor's question style, then writes a forecast for each upcoming quiz or exam with likely topics, the expected format, and likely questions.

3. Study what matters

Pick an assignment or a topic and Crambly runs a study session. It asks multiple-choice and short-answer questions in your professor's format, focused on your weakest and most-tested topics, and explains why each answer is right or wrong with a detailed side panel. It checks in, changes approach when something isn't clicking, and remembers what you missed.

What you'll see

• A readiness score for every upcoming assignment.
• Mastery bars for every topic, with flagged aspects to fix.
• A Saved sidebar for explanations you want to keep, organized in your own folders.
• A profile of how you learn best.
