At SDE, we prioritise your child's success by offering a wide range of 11+ Courses and 11+ Mock Exams specifically designed for students preparing for the 11+ exam.
Our 11+ Courses cater to students in Year 4 and Year 5 at school, providing tailored preparation to suit their individual needs and age.
For students attending the SDE Year 5 11+ Course, we also offer 11+ Refresher Courses to help reinforce key concepts, targeted 11+ Workshops to address your child's weakest 11+ subject and a range of area and school-specific 11+ Mock Exams to build confidence and familiarity with the 11+ exam format.
In addition, we provide a variety of materials available for purchase through our Online Shop, ensuring that your child has access to the best resources for their 11+ preparation.
SDE's Year 4 11+ Foundation Courses which are followed by the Year 5 11+ Course (typically 34 weeks) are designed to thoroughly prepare your child for all aspects of the 11+ exam(s) they are studying for.
SDE's 11+ Mock Exams take place throughout the spring and summer. They are held in Exam Halls and are designed to emulate, as far as reasonably practicable, all aspects of the 11+ exam your child is preparing for, including the test style, format, content, level of difficulty, timing and administration.

Parents are drawn to SDE tutoring largely through positive word of mouth, here's why:
With over 37 years of experience in 11+ tutoring, we have mastered our own, proven techniques that will teach your child how to correctly and speedily approach 11+ English, Maths, Verbal Reasoning and Non-Verbal Reasoning questions.
We have spent many thousands of hours writing and refining the 11+ Course structure, lesson plans and materials taking account of all known requirements of the 11+ tests. All the materials written for the SDE 11+ Course are unpublished and are therefore only available to students attending SDE classes.
We offer a small group tuition format. Additionally, each Tutor is aided by a trained SDE Tuition Centre Assistant to help them with administrative matters (such as marking the in-class test), allowing the tutor to fully devote their attention to teaching your child. In Year 5, we also offer subject-centric 11+ Workshops to suit the specific needs of your child, focusing on their weakest 11+ subject.
At SDE, we hold ourselves to the highest standards when it comes to teacher recruitment. We handpick only the most experienced, exceptional teachers, who not only possess the necessary qualifications to teach but who are also specialist subject area 11+ tutors.

My son was so happy to have his 11+ tutorial in SDE in last two years and finally passed the 11+exam. The tutors at SDE have much experience for the 11+, and the staff in SDE have always provided a nice service for the parents and students.
My daughter enjoyed the lessons and SDE catered to her needs well. Resources were quite useful and I would highly recommend parents to join SDE for preparing their children for 11+ exam.
We keep busy at SDE always improving our offering and facilities, helping various charities and supporting our community. Keep up with the latest here and on our social media channels.
