I have completed by Bachelor of Science(BSc) in Mathematics from Mar Ivanios College at 2017. Then I completed Bachelor of Education(B.Ed) in Mathematics from Mar Theophilus Training College at 2019. There is an internship during my B.Ed life about 6 months. So I got a teaching experience from the St Mary's and St. Goretti's school of high school students. Then I secured Masters of Science in Mathematics from Mar Ivanios College at June,2021.
While I was doing my Postgraduation, I was taking private tutions for high school students mainly for mathematics. Currenly I am working as an online tutor in online sites like teacheron, doubtbuddy, helloexpert.
