I did my schooling from Bhavan's Vidya Mandir Elamakkara. I'm a graduate in Bachelor of Business Administration from St.Albert's College Ernakulam. I have worked in HDFC Bank Ltd for under an year. I have done a course on digital marketing. And also possess 7 Google Ads Certification, Bing Ads Certification.
I used to help teach my relative who needed special attention as she was a bit autistic. The way of teaching her was not like normal children, I taught her the way she understood usually pictorial representations and thus increased her grasping power and widening her knowledge on the subjects. I used to help her with all the subjects (3rd standard). While acquiring my undergraduate degree, I used to take home tuition for a child of 7th standard from Choice school. The student needed one-on-one attention, as she was unable to study and understand despite going to other tuitions. Witnessing her performance in 7th her parents and she herself insisted me on taking her 8th standard tuition also. The subject was mathematics for both years. I also teach my little sister (13 years younger to me). At younger age I used to teach her all subjects and nowadays I help her with mathematics only. She's now in 8th standard.
