Who am I?
My name is Elias (Eli) Christodoulou. I graduated high school in 2021, with an ATAR over 99. I began tutoring in 2021, during my HSC year. It was then that I discovered my passion for high school tutoring of Maths and Science.
I haven't stopped tutoring since then, tutoring 6-7 days a week, 6-8 hours on the weekends, while completing my undergraduate degree at USYD. I am currently doing my Masters in Mathematics and Statistics. I take joy in seeing my students improve, and understand and apply concepts to an extent they didn't think they could.
I see my students reach new heights, achieving ATAR's over 99 themselves. Most importantly, they achieve entry into the courses they wanted, such as medicine, law, and engineering.
I am dedicated to ensuring every student I have maximizes their opportunity. Everyone is more capable than they think they are, and often needs someone to show them that.
Entering the tutoring scene 5 years ago, I've been both a private tutor and a tutor for a company, and have been fortunate enough to have been running my own tutoring centre "Eli Education" for the past year.
OptiEdu is my attempt at making high quality tutoring accessible to everyone.
