Why quizzes beat rereading your notes

Quizzes work best when they test you on your own material, and an EasyClass-style AI quiz generator can build them from the notes and slides you already have. Answering a question forces recall, which shows you what you actually remember before an exam.

Questions are generated from the files you upload, not from generic templates.
Each question includes an explanation so wrong answers teach you something.
The free plan includes 3 generations per month and browser study with no exports.
Paid plans add export options for your own review and offline practice.

Example intro biology quiz questions

Which organelle produces most of a cell's ATP?The mitochondrion. It carries out cellular respiration, which releases energy from glucose and stores it as ATP.

True or false: animal cells have a rigid cell wall.False. Animal cells lack a cell wall, so they depend on the cell membrane and cytoskeleton to keep their shape.

What is osmosis?The movement of water across a semipermeable membrane toward the side with the higher solute concentration. This is why cells swell or shrink in different solutions.

Why is DNA synthesized in the 5' to 3' direction?DNA polymerase can only add nucleotides to the free 3' hydroxyl end of the growing strand, so the new strand grows in that direction.

Short answer: which phase of mitosis separates sister chromatids?Anaphase. Spindle fibers pull the sister chromatids toward opposite poles of the cell.

How it works

Pick multiple-choice, true/false, short answer or a mix, and how many questions you want.

Take the quiz and review

Answer the questions, read the explanations for anything you missed, and generate a new set when you want more practice.

DeckOwl is not affiliated with EasyClass. It is a separate tool that reads your files and writes questions, explanations and, if you want them, flashcards and mind maps from the same source. You can use it alongside whatever course platform your class uses.

Start with a short quiz on one chapter, check the explanations for every wrong answer, then repeat the questions a day or two later. Mixing question types keeps you from memorizing the wording of a single item.

Frequently asked questions

How many quiz questions should I answer in one study session?

Ten to twenty questions is a good range for most students, because it is enough to find weak spots without leading to fatigue. Review every explanation for the questions you missed before you move on.

Is a quiz better than rereading my notes for exams?

Practice testing usually produces better long-term recall than rereading, because you have to retrieve the answer instead of recognizing it. Rereading still helps as a first pass, but quizzes show you what you can actually produce.

Is DeckOwl the same as EasyClass?

No. DeckOwl is a separate product and is not affiliated with EasyClass. It is an AI study tool that generates quizzes, flashcards and mind maps from files you upload.

Can I export my quizzes to Moodle or QTI?

Moodle XML and QTI 2.1 export are available on the Pro plan at $14.99 per month. PDF and DOCX export are included in the Plus plan at $39 per year or $7.99 per month.
