I am a high performing graduate from Normanhurst Boys High School, completing 16 units with

an ATAR of 99.30. Mathematics and physics both significantly contributed to my success,

requiring an intuitive understanding of the underlying principles and extensive practice. I model

my mathematics and physics lessons based on these principles of success, teaching theory from

strong foundations and building up my students’ confidence with practice material including

exam style questions.

I also find it essential to moderate my content to the level of the student. Anyone can improve

with proper guidance and hard work, and I will put in my best efforts for the success of any
