YEAR 8
MATHEMATICS
Our Objective
The year 8 Mathematics program at Cosmos aims at developing on the fundamental concepts learnt by students in year 7 by providing them with tips and tricks to solve problems more efficiently. Students will be provided with the ultimate combination of our interactive lectures, study material, quizzes, worksheets and continuous formative assessments. They will learn the entire year 8 syllabus as per the latest NSW curriculum in full depth as well as selected chapters from the year 9 syllabus. Students need to attend two classes every week along with an optional doubt clearing and extra practice class every Sunday. Each class is 2 hours long with a 10minute break in between. Students are motivated to keep their assessments up to date on google classroom and parents receive report cards every term containing detailed statistics of their children's test scores. Students can ask our teachers to help them personally with their school homework before/after class hours.

Great experience. Maths teacher Ganesh was very helpful. he spent several hours with my son personally when he was struggling with linear equations and made him very good in that topic. Definitely recommend especially for Maths.

Enrolled my 2 kids in year 7 class. Was unsure about how they will find it as previous experience with other tutoring centers wasn't very good. However, the atmosphere at Cosmos is pretty chill. They take it gently with the students. My kids really enjoy the classes and the Sunday quiz competitions.
Anu Sharma
Very pleased with the tutoring. My kid's marks improved drastically in just a couple of months. Sai and Shariq were extremely helpful. This was the first time that my son was interested to attend tutoring.
Andrew Anthony
Happy with the tutoring. Lots of study material and homework. Sai is very easy to contact and he uploaded more material many times when I requested it for my daughter. Weekend tests have good difficulty and test students understanding slightly beyond their syllabus.
Akshita Kulkarni
Excellent Maths and Science tutoring for high school. will recommend to all for school preparation.

Sai helped my child catch up with the missed syllabus as he joined late. Really grateful. Didn't charge any extra fee although he helped my son one on one after class.
