Sydney tutor in Algebra, Anatomy, Biochemistry, Biology, Calculus, Chemistry, Further Maths, General Science, Geometry, Human Biology, Maths, Maths Methods, Statistics

*99.00 ATAR (2020)*

Hi, my name is Gabriel and I’m a 2020 graduate who achieved a 99.00 ATAR. I studied Chemistry, Biology, English Advanced, Mathematics Extension 1 and 2 as my HSC subjects.

The New HSC Math Extension 1 & 2 Syllabus may seem daunting and challenging, but as your HSC Mathematics tutor, I have first-hand experience in studying effectively and excelling for the New Syllabus. I will work extremely hard to help you navigate the uncertainties and struggles of the New Syllabus. As a tutor, I have access to resources covering the new topics such as Proofs, Vectors, Differential equations and binomial distributions.

In Chemistry and Biology, I ensure that you are well versed in all aspects of each module so that you are able to address every question with the necessary knowledge and examples. During lessons, I especially run through common pitfalls and mistakes to ensure you don't lose marks for silly errors (such as not drawing straight lines in diagrams and not using crosses to plot points in Chemistry graphs!).

My strength as a tutor is to not only teach you the HSC content with great depth, but to provide advice on exam skills and structuring study throughout the year to ensure the best possible results.

Subjects available:

Year 12: Math Extension 1 (2020 syllabus), Math extension 2 (2020 syllabus), Chemistry, Biology

Year 11: Math Extension 1 (2020 syllabus), Chemistry, Biology

Year 10: Math, Science


1-on-1 Lessons (online/in-person)

Group Lessons (online/in-person)



I have experience tutoring in the past year as I ran study sessions after school in preparation for HSC exams. I was responsible for teaching a large group of 25 students where I showcased my public speaking abilities and knowledge of Biology content. These sessions ran weekly for the month of October.
