I found that I might have learning problems some time ago, so I searched on the website and found a free test provided by PowerBrain. After the test, I got a report and was given an analysis on details of my cognitive weaknesses. Then I decided to join 30 one-on-one training sessions (45 minutes per session). The instructors will tailor-make a program for each person according to his profile and progress. They will also explain details of the procedures and their targets during the training sessions. The training sessions were kind of relaxed and I did not feel any stress. After each session, we would have a free talk about things of any interesting subjects.
If you or anyone around you want to improve your cognitive weaknesses in areas such as understanding, learning, attention and memory, which affect you throughout your whole life in different aspects, I will recommend this training program.
