Each time you access our Services, you shall be deemed to have accepted the latest Terms and Conditions.

    Money Back Guarantee Offer

          This Money Back Guarantee (“Scheme”) is offered by OKS Education Private Limited (“MarkSharks”, “we”, “us” or “our”) to its paid subscribers                      (“Subscriber”, “you”, “your”) in accordance with the terms and conditions herein below.




  • The Scheme is only valid on subscriptions purchased between April 1, 2018 and Feb 28, 2019 (both days inclusive) by paying the full subscription amount. In case of any part payments, you shall not qualify under the Scheme. However, MarkSharks, in its sole discretion, reserves its right offer the Scheme to any subscription purchased before April 1, 2018.


  • You can avail this Scheme only if you are enrolled in a school following the Central Board of Secondary Education curriculum. In case your school follows any other curriculum, please do not subscribe. In case you still do, any subscription fee paid to MarkSharks shall be non-refundable and you shall be excluded from participating in this Scheme.


  • In order to be successfully enrolled in the Scheme, you will have to send a copy of your official marksheet from the previous academic year. Unless a copy of the marksheet is received, you shall not be eligible to avail any benefit under the Scheme. The marksheet can be sent via the MarkSharks mobile/tablet application (“App”) or by e-mailing it to marksheet@marksharks.com. In case of any name mismatch or submission of false/fake mark-sheets, MarkSharks shall have the right to revoke your benefits under the Scheme as well as cancel your subscription without any refund whatsoever. MarkSharks also reserves its right to verify your marksheets before processing any refund claims. For such verification, you shall, upon MarkSharks’ request, provide an authorisation letter to your school to release a certified copy of your marksheet.


  • Upon activating the subscription, you undertake to complete a minimum coursework before appearing for your exams. Such coursework shall include the following:


  • Minimum active usage of 2 hours (i.e. 120 minutes) per week, with at least 30 minutes spent on each subject (Maths and Science). This minimum usage must occur every week from the date of purchase of the subscription till the date of the final exam for Maths and Science.  

  • The Scheme entitles you to a full refund of the annual subscription fee only if you obtain a lower cumulative score in Math and Science as compared to the ones mentioned in the marksheet submitted at the stage of enrolment in the Scheme.

  • Illustration: Priyanka uses the app for 140 minutes each week, spending 50 minutes on Science and 90 minutes on Maths. Last year, her marks in Science were 65/100 and Maths were 60/100. This year her marks in Science are 60/100 and Maths are 60/100. She is thus eligible for the money back guarantee. Sonia got lower marks in both Maths and Science than last year, and used the app for 150 minutes each week but uses Science for all 150 minutes. Thus, she is not eligible for the money back scheme because she hasn’t used Maths for at least 30 minutes per week. Rohan used the app for 140 minutes each week, with 70 minutes on Maths and 70 minutes on science. His score in Maths last year was 60/100 and Science was 50/100. This year, his score in Maths was 70/100 and Science was 45/100. Since his combined score is higher than last year’s (115 > 110), he is not eligible for the money back guarantee.

  • Notwithstanding anything stated herein, MarkSharks shall account for the time spent on both Maths and Science based on usage data, which is visible to you through the “User Analytics” section in the App.

  • If you are eligible for a refund under this Scheme, you must email both your current years mark sheets and previous year’s mark sheets of both Maths and Science to marksheet@marksharks.com within 15 days from the date of receipt of your examination results. You must also include your email, mobile phone number, and name. In case you request the refund after the 15th day herein, MarkSharks shall have the sole discretion to determine whether to process and approve your refund or not.


  • Subject to MarkSharks’ approval, you may also be entitled to forfeit the refund amount in exchange of a full year’s subscription for yourself for the subsequent academic year.


  • You agree that only 1 refund shall be permissible against 1 subscription. Even if the subscription is used by multiple subscribers, the refund shall be available only to the subscriber whose marksheet is submitted in accordance with this Scheme.


  • In the event MarkSharks approves your refund in accordance with the terms of this Scheme, your payment shall be processed by way of cheque or a direct refund into your account/debit or credit card which was used to pay for the subscription. The mode of refund shall be decided at the sole discretion of MarkSharks. You agree and confirm that any refund due to you shall be subject to deduction of all payment gateway charges and applicable taxes.

  • The money back guarantee is applicable only to the cost associated with the MarkSharks software application. Any hardware purchases like tablets are not included in the money back guarantee and the purchase is not refundable through the company.


  • Any information received by MarkSharks in relation with this offer shall be privileged and confidential and remain the exclusive property of MarkSharks. Notwithstanding anything contained herein, you specifically allow MarkSharks to use aggregated data, statistics and analytics for marketing and operational purposes without publically disclosing your name and result. MarkSharks may, however, seek your specific consent should it want to make your name and grades public in order to market the App and its content. 


  • MarkSharks say shall have the final authority in case of any difference in interpretation of the terms of this Scheme. You unconditionally agree that in case two possible interpretations of this Scheme are possible, the one more favourable to MarkSharks shall be the correct and valid one.


  • These terms are applicable in consonance with and are supplementary to the Terms of Use and Privacy Policy (hyperlink the Terms of Use and Privacy Policy) of MarkSharks. Regardless of whether you are entitled to a refund pursuant to this Scheme or not, you undertake and agree to unconditionally comply with the Terms of Use and Privacy Policy at all times.
