AP Biology
The AP Biology exam rewards reasoning as much as recall. According to the College Board, it has two sections of equal weight: 60 multiple-choice questions in 1 hour 30 minutes (50%), and 6 free-response questions in 1 hour 30 minutes (50%) — 2 long questions on interpreting and evaluating experimental results (one with graphing) and 4 short questions on scientific investigation, conceptual analysis, models or visual representations, and data analysis. It's a hybrid digital exam: you answer multiple choice in Bluebook and handwrite free-response answers in a paper booklet. The 2027 exam is scheduled for May 3, 2027.
Also generate a fill-in-the-blank worksheet + answer key (separate page in Word/PDF). No extra AI call.
Teacher mode unlocks on Student Plus / Pro (and Starter / Exam / Semester packs).

The course is organized into 8 units, from Chemistry of Life to Ecology, with Natural Selection carrying the largest weighting range (13–20%).
Study Guide Maker turns your own class materials — slides, text-based PDF handouts, Word docs or notes — into a guide for each unit: an outline, key concepts tagged to the page or slide they came from, a glossary, practice questions and flashcards. Choose the AP/IB level. Then add data and graphing questions from your labs, and practice with the released free-response questions on AP Central.

Biology
Cellular respiration is how cells turn the chemical energy in glucose into ATP. It happens in three stages — glycolysis, the Krebs cycle, and the electron transport chain — and releases carbon dioxide and water as by-products.
Sample output for illustration.
Per the College Board: Section I has 60 multiple-choice questions in 1 hour 30 minutes (50% of the score); Section II has 6 free-response questions — 2 long and 4 short — in 1 hour 30 minutes (50%). It's a hybrid digital exam with handwritten free-response answers.
Eight: Chemistry of Life; Cells; Cellular Energetics; Cell Communication and Cell Cycle; Heredity; Gene Expression and Regulation; Natural Selection; Ecology. The College Board describes this as one possible sequence — your teacher may order them differently.
It creates multiple-choice and short-answer practice questions from your material. For the exam's free-response format, use the released questions and scoring guidelines on AP Central, and add data-analysis questions from your labs.
One unit's worth of your teacher's slides (PPTX), text-based PDF handouts, Word documents or notes. Diagrams and images aren't read, so describe key figures in your notes.
