Why practice questions beat rereading

Practice questions show you what you can recall without looking, which rereading never tests. This free AI quiz generator for studying turns your own slides, PDFs or notes into questions, so the practice matches what your instructor actually covers.

Generate questions from the exact PDF, slides or notes your course uses.
Mix multiple-choice, true/false and short-answer questions in one session.
Read an explanation for every answer, right or wrong, to find the gap.
Retry missed questions after a delay, which is when recall really gets tested.

Example chemical bonding practice questions

Why do ionic compounds such as NaCl have high melting points?Strong electrostatic attractions between oppositely charged ions in the lattice take a lot of energy to overcome.

True or false: a covalent bond forms when atoms share electron pairs.True. The shared pair is held between two nuclei, which is what makes the bond covalent.

What type of bond holds the two atoms together in a Cl2 molecule?A nonpolar covalent bond. Both atoms have the same electronegativity, so the shared electrons are distributed evenly.

Why is a water molecule polar?Oxygen is more electronegative than hydrogen, and the bent shape stops the bond dipoles from canceling out.

What holds metal atoms together in a metallic bond?Positive metal ions sit in a lattice surrounded by delocalized electrons that are shared across the whole structure.

Multiple question types

Get multiple-choice, true/false and short-answer questions. Each one includes an explanation, so a wrong answer shows you why the right one is correct.

Built from your material

Upload PDF, DOCX, PPTX, plain text or photos of pages. Photos are read with text recognition, so handwritten-free printed notes work well.

Study in the browser

The Free plan includes 3 generations per month and browser study. No credit card is needed to start.

How it works

Upload your material

Add a PDF, DOCX, PPTX, notes or a photo of a page from your course.

Choose a question type

Pick multiple-choice, true/false or short-answer questions for your session.

Answer and review

Read each explanation, then retry the questions you missed until they come easily.

Each question comes with an explanation, which matters as much as the answer. When you miss a question, the explanation points to the specific idea you need to review, rather than leaving you to hunt through a chapter.

Start with a small set on one topic, check your misses, and generate again on the same material after a day or two. The Free plan gives you 3 generations per month, enough to test a single unit before deciding whether you need more.

Frequently asked questions

How many practice questions should I do before a chemical bonding exam?

Aim for enough questions to cover every bond type and its properties, usually two or three short sets across several days. Retry the ones you missed until you can answer them without hesitating.

Is it better to answer questions or reread notes when studying chemical bonding?

Answering questions usually works better, because you have to retrieve ideas like ionic lattices or electronegativity from memory. Rereading is still useful for checking explanations after a wrong answer.

Is the free AI quiz generator really free?

The Free plan includes 3 generations per month and studying in the browser, with no credit card needed. Unlimited generations start with the Plus plan at $99.90/year or $9.99/month.

Can I export my quiz to another app?

Exports are paid features, so they are not included in the Free plan. Plus adds PDF, DOCX, Anki and CSV export, and Pro adds QTI 2.1 and Moodle XML.
