Maths, English, of course, then Latin.
Why Labour decided it was elitist and took it off the curriculum seems very short sighted. All schools did Latin back in the day, just the same as EVERYONE did the 11 plus, it was just an exam. You didn't have to go to grammar school. You could have a chance, even if your parents didn't care about you Or not have the ability to sort out the 11 plus applications etc etc.
It's been very useful over the years for translations, meaning of words, stories for dc growing up, Travel is more interesting, medical knowledge with words. Everything!
