Customer voice

Throughout the past year of our son's participation in RISU's critical thinking, we have observed his growth in the way he dealt with challenges, both at his Day school and at home. We're glad that he's building a strong and open mindset, meanwhile, continue to be a very happy boy. This year, our son got accepted to the Gifted program at his school, compare with behind average class progress a year ago, this is huge improvement! Many of the RISU challenges are very interesting (I would say HARD, using traditionally way of solving problems, even for adults). It's fascinating to see kids in the RISU class approach them and break down the problem from some very different angles. I strongly recommend this to other kids, actually even for myself!
