Ms. Emel is honestly the only reason I managed to get an A* in English First Language. When I first joined this center, I was failing English and struggling a lot — First Language English felt almost impossible for me. The highest grade I ever managed to get was a C, and even in mocks I only got a B.
But Ms. Emel never let me lose hope. She kept motivating me, giving me advice, and pushing me to believe that I could do better. Her teaching methods and tips were always so helpful and extraordinary, and they really made the biggest difference in how I learned and improved.
When exam time came, I gave it my best shot, and to my surprise, I ended up with an A*. It’s an achievement I never thought was possible, and I know it wouldn’t have happened without Ms. Emel’s guidance and encouragement.
She’s someone who inspires her students to keep trying, even when it feels impossible. I’ll always be grateful to her for helping me reach something I never thought I could.

Asia Pacific International SchoolI struggled a lot with Additional Mathematics in Year 10 as I was involved in many activities and couldn’t keep up with the syllabus. When I joined Visi Genius in Year 11, Mr Alvin completely changed my learning experience. He not only taught me how to approach and solve Add Maths questions clearly, but also constantly encouraged me to never give up, even when things felt overwhelming.
With Mr Alvin’s guidance, I improved significantly — my grade went from D in Trial Exam 1 to C in Trial Exam 2. More importantly, he helped me build confidence in a subject I once thought I would never do well in. I never believed I could achieve an A for IGCSE Additional Mathematics, but in the end, I scored A, from D to A in just one year!
I am extremely grateful for Mr Alvin’s patience, dedication, and constant support. His guidance truly played a huge role in helping me achieve results I once thought were impossible.

Sri KL International SchoolBefore joining Mr Alvin’s Additional Mathematics classes, I was an average student aiming to score an A*. Under his guidance, my understanding of Add Maths improved steadily. His teaching style may not be flashy, but he is very patient and clear when explaining concepts, especially when I have doubts. He is also very approachable, making it easy to ask questions without hesitation. Mr Alvin provides a lot of practice questions, so I never had to worry about lacking exposure to exam-style questions. With his consistent support and guidance, I eventually achieved an A* with a score of 96 in Additional Mathematics.
Daren Lim, A* for Add Maths (2025)
Sri KL International SchoolMr. Alvin has been more than just a maths teacher to me, he’s been like a friend and a mentor. He taught me from Year 6 all the way to Year 11, and he was the one who encouraged me to take up Add Maths even though I wasn’t confident at first. I actually started Add Maths two terms later than everyone else, which made it even tougher.
When I started, I struggled a lot. I got an F in my first term, then a D, then a C. Honestly, I felt like giving up. But Mr. Alvin never stopped believing in me. He kept pushing me, reminding me that I could do it if I put in the effort.
Two terms later, I got an A in my mocks, and in the actual IGCSE, I ended up with an A* in both Maths and Add Maths. Looking back, I know it wouldn’t have been possible without him.
Mr. Alvin isn’t just a teacher who teaches formulas and methods he’s someone who motivates you, supports you, and makes you believe in yourself. I’m really thankful for everything he’s done for me.
Sachvin, A* for Add Maths & Ext Maths (2025)
Asia Pacific International SchoolI’m truly grateful to have had Mr. Alvin as my Add Maths teacher for almost a year, especially since my school only started teaching Add Maths in Year 11. Learning and mastering the entire IGCSE Add Maths syllabus within just one year was very challenging, but with Mr. Alvin’s excellent teaching, I achieved 92% in my IGCSE results. His clear explanations made complex concepts much easier to understand, always focusing on the most important points in the fastest and most effective way. Despite travelling over an hour to the centre, it was definitely worth it. Affordable fees, a supportive environment, and a dedicated teacher—I highly recommend Visi Genius Tuition!

Yee KaeLyn, A for Add Maths (2024)
Sri KL International SchoolWhen I first encountered secondary level maths in Year 7, I found myself asking my peers and seniors to help with all my assignments, to teach me and guide me through every step, and still failed almost every test and exam I took. When my mum first decided to put me into Mr. Alvin’s class in Year 9, I felt like I had to put up with even more math in my weekly routine. However, I eventually found that it was the safe environment I needed to process and perfect my concepts of math, alongside peers who made the class even more friendly and inviting. I am forever grateful for Mr. Alvin for putting up with my careless mistakes and countless repeated errors, and for explaining each method and calculation in a way that even a student that was far behind like myself could understand. Thank you Mr. Alvin for all your efforts, and for teaching me how to enjoy the practice of Maths, bringing me from a D to an A* in my results!

Sri KL International SchoolI’m so lucky to have a tuition teacher like Mr Alvin as he is a teacher that is very patient, every time when I don’t understand why and how the question is solved Mr. Alvin will then explain to me with a different style and method until I fully understand about the question, then he will only move on to the next one. He is also a very kind and interesting teacher and in every class, Mr. Alvin will guarantee you with a joyful smile which makes the class not dull but full of happiness. Mr. Alvin will also take some of his off days to give me extra classes .THANK YOU SO MUCH MR ALVIN ❤️
Desmond Kum, A for Ext Maths (2023)
HELP International SchoolI started having classes with Mr Alvin in Year 9. At the time, I struggled with understanding the concepts which made me dread doing math. However after having classes with Mr Alvin, I was able to understand difficult concepts easily and I felt more confident as Mr Alvin’s teaching was extremely concise. Additionally, in classes, he would write organised notes that are straightforward which are easy to grasp and of course extra work to solidify the concepts. During my IGCSE journey I had to switch syllabus midway, but with Mr Alvin’s guidance, the transition was smooth and easy as Mr Alvin was able to prepare me fully in the short amount of time available. I believe without Mr Alvin’s motivation, patience and effort, I wouldn’t be able to strive in Maths. Thank you so much Teacher Alvin for squeezing in extra classes and believing in me!

Sri KLMr.Alvin is a great teacher who helps me a lot in Add Maths. I have just got my results recently with 8As. Of course, I got an A* for my Add Maths.

Mr. Alvin teaches with patience and dedication, he is a very friendly person which makes me feel not shy to ask questions. Mr. Alvin had also furnished the centre that creates conducive environment for student to study in. Not to mention, the centre is very clean too. He is also following the SOPs rules strictly during the pandemic and I felt safe while having tuition. Thanks a lot, Mr. Alvin.
