You can please send GOLDEN SUNRISE and STUDY SERUM to learning skills for social science.
Also you can make him study in parts….i had a tendency to forget lessons in my childhood especially long answers in history and Science.
My mother helped me to overcome this. Just sharing this with you.
She made me read one line. Repeat it twice in mind. Then read the second line. Repeat 1st and 2nd line.
Then read the 3rd line. Repeat 1st, 2nd , 3rd line…in mind. And so on.
Initially i used to find this tedious but later i enjoyed it. Speed increases then to do paragraphs repeating instead of lines.
Increase his BRAIN SERUM and PERFECT HEALTH SERUM intake too.
