I Used an AI Tutor for a Month. Here Is Where It Fell Flat

The setup
First-year statistics, a subject I was quietly falling behind in, and one rule: every question I would normally ask a tutor or a friend, I asked the model instead. That meant concepts I had missed, feedback on working, quiz questions on the week's material, and explanations of why my answer was marked down. For a month it replaced the person I bothered at midnight.
Where it was genuinely brilliant
- Patience without embarrassment. I asked the same question four different ways and never once felt stupid doing it.
- Available at 1 am. The exact moment panic sets in is the moment a human is unavailable.
- Step-by-step on demand. It would stop exactly where I got lost, then continue from there rather than restarting the whole explanation.
- Infinite practice questions. Generate ten problems, mark them, generate ten harder ones, no waiting for a worksheet.
Where it fell flat
The failures were not random, they had a shape. It was confidently wrong about specific things: a formula it rearranged incorrectly, a marking criterion it invented, a reference to a textbook chapter that does not exist. Left unchecked, those slips would have quietly cost me more marks than the concepts I was struggling with in the first place.
It also had no idea what I actually understood. It would happily explain a concept I had already nailed while skipping the small gap that was costing me marks, because I never told it the gap either.
And it could not feel the exam. It has no sense of what the marker wants, which topics are worth the most, or how the course differs from the standard version of the subject.
The rules I ended up keeping
- Ask it to show working, never just an answer, so I can spot the slip.
- Cross-check any formula or definition against the lecture notes first.
- Tell it what I already know so it stops explaining things I have.
- Use it for practice and explanation, not for what the assessment actually rewards.
- Take anything it says about deadlines, criteria or references back to the unit guide.
What I would tell a friend
An AI tutor is the best study support you can get for free at any hour, and it is useless at the part of university that matters most, knowing what your particular class expects. Use it for the mechanics and keep your real questions, the ones about marks, workload and what to prioritise, for humans who know the course.
