Why a reviewer works better as a quiz

Rereading a reviewer quiz maker workflow sounds simple, but most students recognize their notes without being able to explain them. Turning your reviewer into questions forces active recall, which is the part of studying that tends to show you what you are missing.

Generate quizzes from your own reviewer, not a generic question bank
Mix multiple-choice, true/false and short answer questions in one set
Read a short explanation for every answer, right or wrong
Export to PDF or DOCX on Plus, or QTI 2.1 and Moodle XML on Pro

Example biology reviewer quiz questions

True or false: animal cells have a rigid cell wall.False. Only plant, fungal and some bacterial cells have cell walls; animal cells rely on the cell membrane alone.

Which molecule carries genetic instructions from the nucleus to the ribosome?Messenger RNA (mRNA). It copies a gene's DNA sequence so the ribosome can read it and build a protein.

In passive diffusion, which way do molecules move?From higher concentration to lower concentration, down their gradient, without using cellular energy.

What is the main job of a ribosome?It builds proteins by translating mRNA sequences into chains of amino acids.

Frequently asked questions

How many questions should a reviewer quiz have?

A single section of review notes usually works well with 10 to 20 questions, enough to cover the key terms without overwhelming one session. Remove any question that tests trivia rather than an idea you need to understand.

How should I use practice quizzes when reviewing for an exam?

Answer each question before checking your notes, then read the explanation for every miss. Retake the missed questions a day or two later to confirm they have stuck.

Can I export my quiz to Word or Moodle?

DOCX export is included in the Plus plan, and Moodle XML and QTI 2.1 export are available on Pro. The free plan lets you study quizzes in the browser without exports.

Is there a free plan, and do I need a credit card?

The free plan includes 3 generations per month and in-browser study, and no credit card is needed to start. Students with a school email get 40% off paid plans.
