If you feel your son is smart but unfortunately his educational level is not that great, I would like to inform you that I have the solution.
Instilling self-confidence
Instilling a love for challenge and perseverance
Making the student eager to do his homework
Love for homework and the desire to do it
Mastering multiplication and division tables, decimal and fractional numbers, and digits
Memorizing English letters, simplifying grammar, and learning it easily
In short, I have your solution.
Your son is a responsibility, and God willing, we will be up to the responsibility.
