Have to declare a bias here as my DS is at MTS and he's loving it. Feel free to PM me with any questions that you have about the school.
I could rave on about the results, the quality of care, the range and quality of additional activities .....
Clearly you have to be happy that it will address the needs and aspirations of your DS.
If it's close too then even better.
I second manicmum!
Your DS will no doubt be offered a 10% major scholarship at MTS.
He will join a group of Y7, Y8 and Y9 Scholars and go on a Scholars trip every half term. My son is part of this programme and LOVES IT!! The enrichment programme is extremely well managed and really stretches them. They're fun as well as educational - last summer, they finished the term with tickets to a dance show!
The boys are streamed in Y9 so your son will be in a class with other Scholars and the brightest boys which form their Oxbridge pool.
My DS will take his IGCSEs in Maths and French a year early.
It really is a fantastic school which I find hard to find fault with. The online weekly magazine, Scissorum, will give you an insight into the School's ethos as well as the Scholarship Programme.
Good luck with your decision.
