Being a teacher is not an easy task. Teaching profession brings with it lots of responsibilities and challenges. But there is nothing wiser than teaching.It is the way of motivating and shaping the character as well as future of a student.
i have tutored mostly high school students from a very young age. Apart from being their tutor i also guide them how to handle real life problems confidently and be strong and independent. I also have fun with them and sometimes i run out of time to spend quality time with them.Basically,I enjoy sharing experiences and learning from them as well.
