Our Objective

The year 12 Chemistry program at Cosmos aims at helping students understand all the concepts in Chemistry in detail and score maximum marks in their assessments and final exam. We achieve this by providing them with the ultimate combination of our interactive lectures, study material, quizzes, worksheets and continuous formative assessments. Students learn the entire year 12 Chemistry  syllabus as per the latest NSW curriculum in full depth. Students need to attend one class every week along with an optional doubt clearing class every weekend. Each class is 2 hours long with a 10-minute 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.
