Hi! I'm Rhys.

You might not recognise me, but you may have read one of my books. I have written more than twenty science textbooks including the SASTA Stage 1 and 2 Biology, Chemistry, and Physics Workbooks in South Australia. In addition I have won numerous major teaching awards.

With fifteen years of teaching experience, I understand that every student is different. It doesn’t matter who you are, where you’re from, how little – or how much – you already know. My lessons are tailored to you, helping you realise your potential and achieve your goals.

What students and parents
say about my tutoring

Dear Mr Lewis,

I cannot hope to express all my gratitude and appreciation for you through this one card, but I hope you can understand how much you mean to me and the impact you have had on my life. I once read a quote that said, “a good teacher is like a candle- it consumes itself to light the way for others”. After having you as my teacher over this past year, I have experienced this first-hand.

Your broad and deep understanding allows you to always answer my questions clearly and has inspired me to push myself to gain a greater understanding of all sciences. Your quick facts, witty humour and ability to radiate positivity have made the content so engaging and made every lesson something to look forward to.

As well as being a highly intelligent person, you have shown me how exceptional of a human being you are. The random deep insights into life, happiness and what to do in the future are lessons that I will hold close to my heart forever as I try to navigate my way through my life. Every single effort you dedicated towards me and the rest of our class will not be forgotten, and I hope the magnitude of these on all our lives is evident. Whatever your future holds, I am sure you will continue to change lives! All the best, I will miss you! 🙁
