If you are planning to send your kids for sat exam preparation to London Academy, be advised that they are not at all the best choice. They are not coordinated at all. They don't give any advise on the registration date of the exam (which you may miss the dead line for the online exam registration). Their teachers are some times late or even miss classrooms. They are very very expensive.
In addition I asked them the fee for abacus (Math) and told me 175 QR/Hr and when I went to Global Education Center (near Old airport) the fee was 350 QR/MONTH. Meaning approx 44 QR/HR.
Bottom line is that don't send your kids to London Academy and try to find another center.
