Well, I thought I would send him to a public college, but after we had a meeting with the college head who came to DS's school I'm not so sure. The college is split into two parts and the one next to us doesn't have any foreign languages (except English) for the first two years
, while the other one has one . She didn't seem to think it would be a problem for those kids who would go the one closer to us 
Yes, he's in a public school, we're by Bastille. I just had a look at what they're doing right now and they are just starting fractions
-as in colouring 3/4 of a square etc, so very, very basic. So it's lots of controls, learning by rota etc, but at the same time it doesn't seem very challenging, tbh.
DS is bored and not very motivated. At the same time he does a lot of daydreaming in class- whether that's a cause or an effect, I'm not sure. He gets 10/10 and 9/10, with occassional 8/10, without any effort at all. I have to admit to just leaving him to it, but on reflection I might do some stuff at home and see whether that will motivate him a bit. So, yes, perhaps a private college would be a better choice. Are they very expensive?
