i just want toknow what to put as my first choice
If you mean KEHS (Independant School) you should not but this school on your LEA form.
If you mean KEGS (State grammars) then I donâ€™t know of any entrance exam *less* predictable.
However, for any schools which you have to enter on your LEA form then you should put them in the order of your preference. No other considerations are relevant, providing only that you have enough space to express your preferences on the form.
Excuse brevity â€“ iPoding.
