Thank you so much sir I'm a maths student but I like to watch your videos. I'm very lonely child at all the time because my mother has left from my life 3 months before my o/l exam.Then I'm so sad, mourning and sorrowing about my life because I don't have anyone like elders as my mother to tell about my problems.I'm getting so willingness,happiness and good achievements through your videos.Once again thank you so much sir so it's my ambition to be a combined maths tuition teacher in my future.
