so they will not necessarily follow the same format as the 11+.
One GS (which is also a language school) I know set exams in:
Another GS set exams in
sciences ( I cannot remember if it is one exam for all the three sciences or one exam in each science)
The format of the exam will be explain in the convocation letter that you will receive... or if you are to impatient to know before getting this letter, try to ask the school directly.
Best wishes to your DC!
