SD will allow a student to re-do any completed lesson/s with the permission and approval of his or her teacher. Such requests should be made by the teacher and action will be taken only upon the teacher's instructions. If there is any special reason to re-do any lesson, please feel free to share it with us and we shall review it on a case by case basis to maintain fairness in the SD Rankings.

Should you have any further enquiries, please feel free to contact us at sd.

Last year we identified this problem and have implemented the following:

• Advanced Encryption. We improved our encryption so now people cannot copy and paste the answers. This was the main way students cheated. We solved it.
• Illegal disconnection. The new version of Learning Management System detects illegal disconnection, and stops it.
• No Multiple Windows. Students see disordered code if they try to use browsers’ open link in new window function.
• No Duplicate Login. We have eradicated the ability to login SD with different browsers or PCs and just copy the answers from one to the other.
• No Logout in Lessons. If they close the browsers, their answers will still be recorded.
• Posting Answers on websites. Any reports coming to us are followed through. We try to discourage and warn them before we take actions.
