PSLE Maths Tutor App is an on-line tutoring service designed to help students to get guidance on their Maths problems at just a finger touch. They get a quick video explanation on how to solve specific Maths problems anywhere and anytime. No long-winded explanations-just short and to the point. If a student is unclear, he just plays the video again or pauses it at important points. Students can send in problem sums and some of them will be selected to be answered. Optimal Learning Hub aims to make learning easy and fun.
