Our Philosophy

It is the belief at Infinity College that a positive learning environment encourages quality learning of all students. A positive learning environment creates pleasurable learning. “What we learn with pleasure, we never forget.” – Alfred Mercier. When students start to taste the happiness in their study they will have the motivation to learn more, through reading, researching and discussion in class. When they understand the topic they would definite remember them for a much longer time.
Our teaching philosophy is to enable all our students to reach their optimum academic performance with support and encouragement from our teachers who inspire students to be lifelong learners. The “Review of Selective Education Access – Findings and Action Plan” published in December 2018 had highlighted the action to “Reduce predictability and coachability” of the assessment tests. Infinity College has been well positioned with the emphasis of building students’ skills in various focus areas for them to apply to a wide variety of question types, rather than simply working on repetitive practice questions.
