Legal
In effect from 19 July 2026. Version 2026-07-19.
FullMarks is operated by OC Research Pte. Ltd., based in Singapore. These terms are the agreement between you and us for your use of fullmarks.sg.
By creating an account or using the service you accept these terms and our Privacy Notice. If you do not accept them, please do not use FullMarks. We record the version of these terms you accepted when you signed up.
If we change these terms in a way that affects you, we will change the date at the top and tell you in the app before the change takes effect. If you keep using FullMarks after that, you accept the new version.
FullMarks helps students in Singapore practise for their exams. You answer a question, and FullMarks marks your answer against the marking material for that question and explains what you would have gained or lost marks for. It also has a tutor that answers questions about your subjects.
FullMarks is a study tool. It is not a school, an exam board, a tuition centre or a teacher, and it is not connected to any of them. It does not award real grades and it cannot promise you a result in a real examination.
You must be at least 13 years old to use FullMarks. By creating an account you confirm that you are 13 or older. If we find out that an account belongs to someone under 13 we will close it and delete the data on it.
If you are under 18, we encourage you to tell a parent or guardian that you are using FullMarks. A parent or guardian can contact us at any time about an account belonging to a student in their care.
You create and access your account by signing in with Google. There is no password on a FullMarks account, and we will never ask you for one. This means keeping your Google account secure is what keeps your FullMarks account secure.
Your account is for you alone. Please do not share it, and do not let someone else use it. Tell us at support@fullmarks.sg if you think someone else has got into your account.
Give us accurate information. If you tell us the wrong school level, the questions you are shown will be wrong for you.
Please read this section properly. It is the part students most often misunderstand.
FullMarks marks your answer using AI, guided by the marking material we hold for that specific question. AI marking can be wrong. It can miss a point you did make, award a point you did not make, or explain something incorrectly.
A mark from FullMarks is guidance to help you study. It is not your grade, it is not a prediction of your grade, and it carries no weight with any school or examination board. Where something matters, check it against your syllabus, your notes and your teacher.
A score appears only where we have identified the question and hold marking material for it. Where we cannot identify a question with confidence, FullMarks gives you a teaching answer instead and labels it as teaching rather than pretending to mark it. Teaching answers are explanations, not scores.
The tutor is also AI and has the same limits. Do not rely on it for anything outside studying, and never for medical, legal, financial or safety questions.
The questions, marking material, explanations and everything else you see in FullMarks are for your own personal study.
You agree not to:
We may limit or close an account that breaks these rules, or where we detect automated extraction of our material.
Your answers and photos stay yours. By submitting them you allow us to process them for the purpose of running the service, which means sending them to the AI services that mark them and returning the result to you. The Privacy Notice sets out exactly where that content goes and how long anything is kept.
Please do not put personal information into an answer, a photo or a support message when the question does not call for it, whether it is about you or about somebody else.
FullMarks has a free plan with daily limits, and paid plans with higher limits and more features. What each plan includes and what it costs are shown in the app before you pay.
Prices are shown in Singapore dollars and include any taxes that apply. The price you see before you confirm is the full price we will charge. Your bank or card issuer may add its own charge for an international payment, because our payment provider processes payments outside Singapore. That charge comes from your bank, not from us.
A paid plan renews by itself at the end of each period, and your card is charged again, until you cancel it. A monthly plan renews every month, and a yearly plan renews every year, on the same date. It renews at the price shown when you subscribe, unless we have told you in advance that the price is changing.
If we ever raise the price of a plan you are on, we will tell you before it takes effect, and you will have the chance to cancel before you are charged the new amount.
You can cancel at any time from your profile in the app. There is no cancellation fee and you do not need to contact us or explain why.
When you cancel, your plan stays active until the end of the period you have already paid for, and it does not renew after that. You do not lose access the moment you cancel.
We do not refund payments that have already been made. You do not lose anything by cancelling, because your plan keeps running until the end of the period you have paid for. You are never charged for time after you cancel, and you are never cut off from time you have already paid for.
If you were charged in error, charged twice, or something has gone wrong on our side, that is different. Write to support@fullmarks.sg and we will put it right.
If a payment fails, we may retry it and we may pause your paid features until it goes through. Your account and your practice history are not deleted because of a failed payment.
FullMarks is being built and improved all the time. Subjects, papers, features and limits will change as we add verified material and correct mistakes we find. We may add, change or remove parts of the service.
We try to keep FullMarks available, but we cannot promise it will never be down. We may take it offline for maintenance, or to protect students, our material or the security of the service.
If we remove something significant that you are paying for, and that materially reduces what your plan gives you, write to us and we will make it right.
You can close your account at any time. Open Profile in the app and choose Delete my account. Your account and your practice history are removed straight away and this cannot be undone. If you are on a paid plan, it stops at the same time, and the rest of the period you have paid for is not refunded. If you only want to stop the renewal, cancel the plan instead and keep your account until the period ends.
If you cannot sign in, write to support@fullmarks.sg and we will close the account for you within 30 days.
We may suspend or close an account that breaks section 6, that is being used to harm other students or the service, or where we are required to by law. Unless the reason makes it inappropriate, we will tell you why and give you a chance to respond. If we close a paid account for a reason that is not your fault, we will refund the unused part of what you paid.
We provide FullMarks with reasonable care and skill. Beyond that, the service is provided as it is, and we do not promise that it will be free of errors or that the marking will always be accurate.
We are not responsible for examination results, school outcomes, or any decision you make based on what FullMarks tells you. That is why section 5 asks you to check anything that matters with your teacher and your syllabus.
Nothing in these terms limits any responsibility that cannot be limited under Singapore law, including responsibility for death or personal injury caused by our negligence, or for fraud.
Subject to that, if we are found liable to you for anything connected with FullMarks, our total liability is limited to the amount you paid us in the 12 months before the event that gave rise to the claim.
These terms are governed by the laws of Singapore, and the courts of Singapore have jurisdiction over any dispute arising from them.
If part of these terms turns out to be unenforceable, the rest of them still apply.
