Making practice questions from your own PDF

Most students end up with a lecture PDF they never revisit, so a free MCQ maker from PDF turns that file into practice questions before the exam. Upload the document, pick multiple choice, true/false or short answer, and the questions come from your own pages rather than a generic question bank.

Example chemical bonding multiple-choice questions

Which type of bond forms when two nonmetal atoms share electron pairs?Covalent bond. Shared electron pairs are the defining feature of covalent bonding, while ionic bonds involve electron transfer between a metal and a nonmetal.

What type of bond holds sodium and chloride together in NaCl?Ionic bond. Sodium gives an electron to chlorine, forming Na+ and Cl- ions that attract each other electrostatically.

True or false: In metallic bonding, delocalized electrons move freely through a lattice of metal cations.True. The shared sea of delocalized electrons explains why metals conduct electricity and can be hammered into shape.

Which bond is most polar: C-H, C-O or C-F?C-F. Fluorine has the highest electronegativity of the three partners, so the electron pair is pulled strongly toward it and the bond has the largest electronegativity difference.

What is the bond order of the N2 molecule?Three. N2 has one sigma bond and two pi bonds, which makes the triple bond very strong and explains why nitrogen gas is so unreactive.

Explanations for every question

Each multiple-choice, true/false and short answer question comes with an explanation, so you learn why the right answer is right and why the others are wrong.

Built from your own files

Upload PDF, DOCX, PPTX, plain text or photos of pages, and the questions are drawn from the material your instructor actually gave you.

Free study in the browser

The free plan includes 3 generations per month and studying in the browser. Exports are part of the paid plans.

How it works

Upload your PDF

Drop in a lecture PDF, a slide deck or a photo of a textbook page.

Choose a question type

Pick multiple choice, true/false or short answer for the set you want.

Answer and read the explanations

Take the quiz and check the explanation after each question, especially the ones you missed.

Questions built from your material test the exact definitions and examples your instructor used, which is what exams usually ask about. Read each explanation after answering, especially for wrong answers, because the reason a distractor is wrong is often the point of the question.

Frequently asked questions

How many practice questions should I make from a chemical bonding chapter?

Start with a small set that covers ionic, covalent and metallic bonding, then generate more questions on the topics you keep missing. Mixing question types helps you practice recognizing bond types from formulas and from descriptions.

What is the difference between ionic and covalent bonds for an exam?

Ionic bonds form when electrons transfer from a metal to a nonmetal, creating oppositely charged ions that attract each other. Covalent bonds form when nonmetal atoms share electron pairs.

Is the free plan enough to make MCQs from a PDF?

The free plan includes 3 generations per month and studying in the browser, but it does not include exports. The Plus plan adds unlimited generations and PDF, DOCX and Anki export.

Can I export my MCQs to Moodle or QTI?

Moodle XML and QTI 2.1 export are on the Pro plan at $14.99 per month. Plus is $39 per year or $7.99 per month, and students get 40% off with a school email.
