Our son goes to smartum courses. We decided to give it away earlier, because small children quickly grasp everything. The child became much more attentive, began to communicate more with his peers, although before that he was more secretive. We go 1 time a week, it doesn't bother. We will continue to walk, especially since the result is already visible.
We also go to Smartum courses, it's true that the sooner you give it back, the better. We have been driving for 11 months now, we are going to school next year, so to speak, we are well prepared for the academic year. Perseverance has developed, my daughter often expresses her opinion. And in general, I became independent, so we do not regret that we go.
