Winchester College - for the cerebral ?

I forgot to add no drama in the curriculum only as an extra curricular activity although there are at least four plays a term. The recent production of the Mikado was absolutely fantastic worthy of the D'Oyly Carte. Also no music for all only for those who choose to do it before they arrive and I think (you would have to check this) you have to be pretty musical to choose it as an option. Again lots of concerts I cant find this terms program but I think about 20 a term my DH is very musical and he's really impressed with the standard.

No its not the choice for every child and I personally think that even if your DC is very academic its still not necessarily the right choice. But there is not a school out there thats suitable for everyone.
I can only tell you the little I know about science maths etc in my DS's house there seem to be lots doing physics/maths Pre U and hoping to continue it onto university I can't tell you if this is representative of all the boys but my impression is that maths/further maths and physics are very popular in fact looking at their website physics seems to come second after chemistry with regard to the numbers sitting it for Pre U. I think there is a lot of effort to try and raise the profile of DT but the number sitting it for A level are not published on their website they seem to only publish the Pre U results, also many sit maths A level at the end of yr 12 again these results aren't published. When my DS was at prep many of the teachers/parents seemed to believe that Winchester was particularly "big" for science.
Its so hard to know what subjects our children will like as they go through education. My DS is currently very keen on physics (but wasn't at prep) brought about by a wonderful physics teacher, he's now has no interest in geography (my subject so there may be a link there!) and having never been overly interested in MFL's is now learning a new one and wanting to carry it on to Pre U! Maths which is meant to be his real strong point has lost its appeal.
With regard to "famous alumni" I frankly don't give toss how famous or not Winchesters alumni are as I personally think fame is a positive handicap in life and wouldn't wish it on my worse enemy. If your shallow enough to choose a school by its alumni then Winchester is definitely not the right school for you.
IME experience Wykehamists are not brash or one of the lads but thoughtful and polite hardly surprising with the motto Manners Mayketh Man. I think your description "the school is suited for the cerebral, intellectual child" probably sums it up. My DS being a rather cerebral intellectual boy is super happy there and that is what matters to me. The one thing I do hear some feel that team sports are a low priority and I think this is probably true.
Hope this helps.

I know plenty of kids at Winchester, my other son is hoping to go and my eldest got in. Write a balanced question and you'll get a balanced response!

Sorry, but why would you assume a school doesn't cater for engineers, sciences etc? All the good schools will educate your child fantastically well in whatever discipline they choose! Quite frankly, do you have any idea what your son wants to do anyway? Thirteen seems a bit young to know if your son wants to be an engineer. Maybe you should look at him enjoying his time at school rather than thinking of what happens at the other end.

I always think of Wykehamists as dutiful types. Not blokes you would necessarily choose to go and have a drink with alone, a bit dull (and I do have extrensive experience of its almuni). If you look at this here it's remarkable how many of its contemporaneous apparently famous alumni I've never heard of. Quite a contrast with the other big name schools (Harrow, Eton etc) Here is the list for Eton to en.wikipedia.org/wiki/List_of_Old_Etonians_born_in_the_20th_century The last time I visited the school was almost 10 years ago though. So perhaps it's changed.

But I'm sure HappyGardening will be along in a minute to tell you how super brilliant it is.
