We are currently looking at secondary schools for our Year 5 DS. Our local secondary schools offer separate sciences from the OCR 21st Century Science Suite. Our DS is only 10 so career choices are not written in stone, but he is very interested in all things "scientific". Like all mner DC he is very able, having already achieved level 5s. 
I have heard/ read mixed reviews of the 21st Century Science suite, namely that it is good for the less scientifically able but doesn't provide sufficient depth to study sciences at a higher level.
Any first-hand views as to whether it would be appropriate for an able, scientifically minded DC would be gratefully received.
