Yes, AI can make you learn less, but only when it does the thinking for you. In one large randomized study, students with an unrestricted AI assistant did worse on the exam than students who never had it, while students whose AI only gave hints held steady. The fix is to let AI quiz you and check you while you do the remembering and problem solving yourself. The test is simple: could you do it again with the chatbot closed?
What the research found
A randomized study published in PNAS (Bastani and colleagues, high school maths in Turkey, nearly 1,000 students) compared three groups. Students with a plain ChatGPT-style assistant solved 48% more practice problems correctly than the control group. But when the AI was taken away for the exam, they scored 17% lower than students who never had it. A second group used a tutor version set up to give hints instead of answers. They did 127% better on practice problems, and on the later exam they performed about the same as the control group.
Two lessons follow. First, an AI that hands you answers boosts your practice results and quietly removes the learning, which is exactly the trap with exam prep. Second, even the careful version did not make anyone better on the exam in that study, so do not treat AI as a shortcut. Treat it as a way to make your own practice better.
The rule: you generate first, AI checks second
Before you ask a chatbot anything, try to produce the answer yourself. Write what you think the answer is, even if it is partial. Only then ask the AI to check it. Struggling for a minute first is not wasted time. It is the part that makes the answer stick.
Seven ways to use AI that keep the learning with you
For the basics of notes, flashcards and study plans, see our guide on how to use AI to study for exams. These are the habits that protect the learning.
- Ask it to quiz you, not to tell you. Paste your notes and ask for questions one at a time. Answer each before it replies. Ask it to wait for your answer.
- Ask for hints, not solutions. On problem sets, tell it to give only the next small step, and to ask you what you think comes after.
- Explain it back. Write your own explanation of a topic, as if teaching a friend, and ask the AI to find mistakes and missing steps. This is the Feynman technique with a reviewer.
- Find your gaps. Give it the syllabus and a list of what you feel confident about, and ask it to suggest questions that would reveal weak spots.
- Make practice versions of problems. After you solve one, ask for three similar ones with different numbers, and solve them with no help.
- Get a second explanation. If your lecturer’s version did not click, ask for the same idea in plain words, with an example, then close it and re-explain it yourself.
- Plan the work, not the content. Ask it to turn your exam date and topic list into a schedule of study blocks, then adjust it to your real week.
Five ways to use AI that quietly backfire
- Asking it to summarize the chapter instead of reading it. You get the feeling of coverage without the memory.
- Asking for the answer to a homework or practice problem you have not tried. That is the pattern the PNAS study found hurts exam results.
- Trusting it without checking. AI tools can state wrong facts, formulas and citations confidently. Check against your textbook, lecture slides or a worked example from your course.
- Studying only the AI’s version of the topic. Your professor writes the exam, so your course materials are the source of truth.
- Using it to write your notes and never reading them. Creating the notes is part of the learning.
Check the rules for your course first
Some courses and instructors restrict or ban AI tools, mostly for graded work. Studying with AI is a different thing from submitting AI work, but check your syllabus and ask if you are unsure. Do not paste in confidential or copyrighted exam material that your course asks you not to share.
A simple midterm workflow
- List the topics and rate your confidence from 1 to 3.
- For each weak topic, study from your own notes and course materials first.
- Close everything and write what you remember.
- Ask the AI to check it, quiz you on it, and point out what you missed.
- Redo the questions you got wrong a day later, with the AI closed.
If you are short on time, the 48 hour midterm study plan shows how to triage topics before you open any tool.
FAQ
Can I use ChatGPT to study for exams?
Yes, as long as you use it to test yourself and explain what you are stuck on, and you do the recall and problem solving yourself. Also check your course policy on AI tools.
Does using AI to study make you learn less?
It can. In a PNAS study of high school maths, students with an unrestricted AI assistant did better on practice but 17% worse on the exam without it. The risk comes from letting it give answers instead of practicing.
What is the best way to use AI for midterms?
Paste your notes, ask it to quiz you one question at a time, answer before it replies, and have it point out gaps. Then retest the missed items without it.
Can AI make mistakes when explaining topics?
Yes. It can state wrong facts or formulas with confidence, so verify important points against your textbook or lecture slides.
Is it cheating to use AI to study?
Studying with it is generally different from submitting AI-generated work, but policies vary by school and course. Read your syllabus or ask your instructor.
