"What can I say… he’s simply a brilliant teacher. Not only did he give me the avenue to get a Band 6, but he instilled within my class this inexplicable appreciation and love for Physics. He went above and beyond, answering any questions that I had and was always so willing to help. It’s undoubtedly been an honour to have been taught by Williams. Would put..." Read more

"I initially joined at the start of this year after two weeks into the Physics Preliminary course. I had no idea about Physics and had swapped into the course. With no prior knowledge or wanting to do any science, Sigma helped me to better understand the concepts within Physics and led me to be able to be confident in my skills."

"If you were to describe a tuition place which was perfect, Sigma would be beyond that. Chris and Alex are great teachers who explain concepts from the basics, all the way to everything you need to know to ace your exams. The best phys and chem tuition out there, would highly recommend to at least try it out, because otherwise you'd be missing out."

"Sigma is an amazing tutorial service. The teacher Chris is truly amazing as he knows exactly how HSC Marking is done, being a marker himself, and is very thorough in the content that he teaches. The questions that he provides in the booklets range in difficulty and allow you to gain some confidence before challenging yourself. Would 100% recommend."

"Going to Sigma Science has been one of my best decisions. Not only is Chris extremely smart and knowledgable, (he really knows his stuff) he is also without a doubt one of the funniest, kindest and most down-to-earth people you will ever meet. If you're looking forward to studying HSC Physics in a positive learning environment, I 102% recommend Sigma."

"Sigma helped me achieve a band 6 in HSC physics!! Sigma science's notes are spectacular because they are condensed and saved me a lot of time. Chris is an excellent teacher and goes through his notes in detail and answers all our questions. His sample exams are very similar to what we received in the HSC and allowed us to develop our exam skills."

"Attending Chris' tutoring was by far the best decision I made in yr 12. His lessons, practice questions and exams gave me the edge I needed to rank 2nd in my cohort. I know that if it wasn't for him, I wouldn't have been as confident and stress-free as I was entering my Physics exams. Chris is super funny, his humour reminds me of my dad if he taught physics..."

"Don't be fooled by this man's humble appearance... he used his powers to single-handedly transform my mode of existence from a state of utter confusion to literal omniscience- at a reasonable price. A truly dedicated teacher who really knows what he's talking about, and actually cares about his students' progress."

"An absolute legend. Chris' understanding and delivery of Physics content puts him in a league of his own. His genuine and friendly personality really made every lesson a pleasure. Only criticism I can offer is that he should tutor more subjects 😁"
