Ds is in S4 at Shawlands (placing request). I couldn't be happier with the school.
Don't think your dd would be able to do three foreign languages in the timetable but should be able to do everything else. As a matter of course, they do 8 x Nat 5 (if they're capable of Nat 5 of course 
) and 5 x Higher in S5.
They alternate German and Spanish as the 2nd MFL (French or Urdu as the 1st but I suspect your dd won't be doing Urdu). Even years are Spanish, odd years are German.
They pick their subjects at the end of S2 - that's why the school is still able to do 8 Nat 5s.
The problem with Asian gangs was a long time ago - it's amazing how long it takes for a reputation to go away.
The school is very proud of both its ethnic and social mix - it's part of what gives it its inclusive character.
While it expects a lot of its pupils academically, it also encourages sports and artistic interests.
As an illustration of the way they stretch the academic pupils, ds is half way through the Maths Higher Curriculum already and his maths teacher says they'll be starting on Advanced Higher in September. One of the boys in his class sat his Nat 5 last year (ie in S3) and got the top mark in the Prelim 
He's sitting Higher this year.
Ds was part of the School of Rugby for his first two years (part-funded by the SRU, open to both girls and boys - even those new to the sport) which meant that two of periods of PE and one period each of English and Maths were given over to rugby (didn't cause him any problems - he was/is in the top set for both English and Maths). There is also a School of Basketball which I presume operated in a similar way.
Apparently an S2 girl is also a talented runner who won a Scottish silver medal in the age category above her.
There is also a strong tradition of public speaking and debating.
