How a quiz generating application fits into studying

Studying from a 40-slide deck the night before an exam usually means rereading and hoping it sticks. A quiz generating application changes that by turning the same material into questions you have to answer, which is closer to what exams actually ask.

Questions come from your own lecture notes, slides and readings
Each multiple choice, true/false and short answer item has an explanation
Photos of printed or handwritten pages are read with text recognition
Paid plans export to PDF, DOCX and Anki, and Pro adds QTI 2.1 and Moodle XML

Example biology quiz questions (cell structure)

Which organelle produces most of a cell's ATP?Mitochondria. They carry out most of cellular respiration, and the inner membrane is where most ATP is made.

True or false: animal cells have a rigid cell wall.False. Only plant cells, fungi and bacteria have cell walls, so animal cells rely on the plasma membrane for shape support.

What is the main job of the rough endoplasmic reticulum?Making proteins for secretion or for membranes. Ribosomes stud its surface, which is why it looks rough.

Why does the nucleus have a double membrane?The nuclear envelope separates DNA from the cytoplasm. Its pores control what moves in and out of the nucleus.

Which process moves water across a membrane toward higher solute concentration?Osmosis. Water moves toward the side with more solute, which evens out the solute concentration on both sides.
