Hello Kans ,
No the cost is about 10000 per kid per month, and for you to confirm about the net cost i will suggest you to visit the school website www.lebocage.net i'm sure they will help you out.
For further education , we have around 5 official institutions that i can say are reliable and their degrees are recognised.
And if your children want to pursue their career in england. FOr someone from here , i believe there is no big formalities when going to study in the UK.
I sincerely dont know the situation in your country. But Mauritius tends to be COOL & RELAX. Yet there is a whole lot of competition regarding professionals. The area where it might be tough is purchasing power. Visiting mauritius is a COOL factor ! but living its a little tough . Not discouraging you , but showing you the true colours.
Now Kans lets be realistic here. With globalisation everywhere its gonna be like this. Yet with mauritius i believe its going to be a better place than elsewhere.
For your kids and your professional life :: its a considerable jump.
