Winston is a really great tutor! In addition to knowing his stuff well, he is patient, supportive and makes it easy to ask questions. The lessons are very engaging so you never get bored or lose focus, and therefore effective for learning both content and good exam technique. Tbh the best tutor I’ve had.

Winston not only helps the students to cover the weakness from any module but also provides outstanding resources. As a student who could not find any merit from science, I can say my science marks and ranks(also a bit of interest) have improved dramatically since having lessons with him.

Winston is an amazing tutor that has very deep knowledge in the chemical ideas relevant to the new syllabus. I definitely recommend his services as I would not have made it this far in my HSC learning without his help and guidance.

Every week I travel approximately 2.5 hours (to and from) to get taught by Chris because he is just that good. Chris is able to clearly explain difficult physics concepts in class and he also took the time to help me refine my answers to past HSC questions – something that tremendously improved my ranks…

Simply amazing. Never stopped helping. The way he teaches concepts and focuses on examination technique was what enabled me to state rank in HSC Physics.

Thank you so much for being such an awesome physics tutor! I could not have done it without your help, so thank you so much!

Truly a fantastic teacher. He knows the ins and outs of the course better than anyone and his passion for teaching really translates, everyone in my class enjoyed his lessons. The best tutor you will find. Enough said.
Rohan Gupta Baulkham Hills High School | ATAR: 99.95 | HSC Physics: 96

I personally found Chris to be the most helpful tutor I had ever been in contact with, not only are his notes great and his teaching essentially perfect but more importantly he’s just a awesome and friendly guy who makes lessons 110% interesting and enjoyable for everyone.

Chris is engaging, witty and knowledgeable – he explained complex ideas in such unique ways that they were simplified incredibly, and provided support by answering questions outside of classes too. I couldn’t thank and recommend him enough!
Sarah Li Kambala HS | ATAR 99.95 | HSC Physics: 93

I remember thinking that a Band 6 would be difficult. However, your amazing teaching style, boundless knowledge and constant reinforcement truly was the main driver behind my results. I moved from rank 100+ in Year 11 to Rank 2 by the end of Year 12.
Steven Kim Baulkham Hills High School | ATAR: 99.80 | HSC Physics: 95

I achieved 87% in my trial exam for Physics, which was 2nd in my grade. Thanks heaps for all the help over the past year, you’ve really helped with my understanding!
Arish Dutt Girraween HS | ATAR: 99.50 | HSC Physics: 93 (Exam mark: 95)

In Year 11, physics was my worst subject- I was ranked 103rd. For my first assessment in Year 12 after starting with Chris, I was ranked in the top 10! Without Chris, I most definitely would not have gotten a band 6 in physics.

Chris has been, hands down, the best physics tutor I’ve ever had. His dedication, attention to detail and the fact that he goes above and beyond for each and every one of his students truly reflects the quality of his services and more importantly, himself as a person.
Kenneth Ngui Baulkham Hills High School | ATAR: 99.25 | HSC Physics: 92

My physics mark was very, very poor in my first year 12 assessment and one of my friends recommended that I try tutoring with Chris. Chris provided us with super detailed notes, he set up extra time before our normal classes to answer our questions for exams and he always made lessons fun.

FAQ
Common Questions
Sigma Science Education is the premier provider for high quality HSC Chemistry & Physics Tuition for High Achieving Students.
All of our teachers are handpicked by the owner, Chris, for their knowledge and their communication skills.
We have fully qualified teachers with 20+ years teaching and HSC Marking experience, but we have also recruited new graduates who have displayed the potential to be an amazing tutor.
We don't just pick our tutors based on their HSC marks as whilst they may have been a good student, this does not make them an effective teacher.
We have turned away many graduates (including state rankers and 99.95 ATAR students) who we feel would not make a high quality tutor/teacher as they lack the required communication skills, only to see them later employed by other tutoring companies...
Weekly classes (term lengths vary from 10-12 weeks).
Weekly homework (with fully worked solutions).
Access to exclusive notes.
Access to extra resources (question banks, past examinations, lesson recordings etc...)
Access to our 24/7 Discord server.
Our class booklets have been compiled using the expertise of university academics, senior HSC markers, HSC Examination writers, experienced teachers and high achieving students.
Class booklets contain all content in the syllabus (and some beyond the syllabus to extend our students and enhance their understanding!).
This theory is broken into digestible chunks and reinforced with consolidation questions and exam-style questions.
Our face to face students have access to our online portal, which contains lesson recordings.
We also live-stream select classes if you are unable to attend our Parramatta campus!
We have multiple students learning with us who live 100+ km from our Parramatta campus!
All payments for our courses are made via credit or debit card through our enrolment portal.
We offer a 2 week money back guarantee period.
If you join and feel like the learning environment is not what you need, we offer a full refund of any term fees paid.
If you decide to discontinue at any stage through the term, we offer a prorated refund.
We offer an Early Bird Discount for each term.
This discount is applied if your payment is made prior to the Early Bird Period Ending.
If you enrol in multiple subjects, the second subject is also a discounted rate.
No.
We do not offer lesson credits for any reason.
You have committed to a position in the class and much like school, if you are absent, you do not receive lesson credits.
We can place you in a different class running the same lesson (if positions are available), you can attend one of the livestream lessons or you can catch up using the lesson recordings.
