Ms Irene is one of those teachers who patiently and thoroughly answers questions to make sure that her students understand the math concepts being tested. The questions that she gives to us are usually slightly harder, to ensure that her students are able to do intermediate, and even advanced questions confidently. To Ms Irene, thank you so much to bring up my math grades in 2025 after I was sick for a long time and had to miss so many lessons and still enabled me to score distinctions for both E Math and A math. I'll miss you😭😭

Teacher Irene has a really approachable nature, and has provided constant support for me when she taught me. Her patience and guidance have allowed me to consistently perform well in my school Weighted Assessments and year end exams. During the O-Level season, she even provided me with more challenging practices that thoroughly prepared me for my exams. This eventually led to me attaining an A1 in both E-Math and A-math. Thank you for making lessons so enjoyable and insightful!

Teacher Irene is a really kind and patient teacher, preparing us adequately before exams. She structures her lessons according to our school's pace, or what we would want to focus on for that particular week. Before tutoring sessions with her, my Math grades were either a B or a borderline pass. I was struggling to keep up with the Mathematics curriculum. After being taught by her, I managed to catch up with lessons and even gained he confidence to take AMath in upper secondary. At some point, I started to love mathematics as a result of her teaching. I graduated with A1 in both Amath and Emath and I can't thank her enough.

Ms Alicia really helped me improve my Amath from a D7 in Prelims to A2 in O levels! Despite me being more quiet, she still reached out to me and asked if I needed any help in Amath, and was very willing to provide support whenever I needed. She also takes the time in class to go through the concepts very clearly every lesson and I really managed to solidify my learning super well!

Before joining Zenith, I was stuck at a B grade for my A-Math in Secondary 3 and 4. However, joining Alicia’s class completely changed the way I learned Math. Within the span of 2-3 months of learning with Alicia, I managed to get distinctions for my A-Math. My love for Math was reignited, and I really enjoyed studying it. She quickly found areas I lacked in and gave solutions, instantly improving my Math. I also had around-the-clock guidance and had my uncertainties cleared outside of lesson time. Her duties go beyond the classroom, as she helped me with school stuff like choosing of my school after O-Levels. She teaches fast yet with precision. If you’re worried that you have no time to catch up, Alicia will help you race to the front no matter your study pace.

Alicia helped me a lot, not just with understanding the concepts but also by ensuring that I practised my time management skills, reduced careless mistakes, and improved in many other areas. She took extra care with topics I was still unsure about and went the extra mile to make sure I was fully caught up and well prepared for my exams. In the end, I improved from an abysmal D7 in prelims to an A2 in the O-Levels! ◡̈

I met Kaiwen when I was struggling with A Math and had no confidence going into TA1. In just two hours, he helped me understand all the A Math topics covered in Term 1. He guided me from not knowing where to begin with a question to confidently identifying the question type and solving it with ease. Kaiwen explains A Math concepts clearly and concisely, making them easy to grasp, which is why I decided to join his class. Throughout my two years in upper secondary, he helped me consistently achieve A1s for A Math. Over time, I gained confidence and even began to enjoy the subject more. I thoroughly enjoy his classes, as he is very patient and attentive to each student. Outside of class, he is always willing to help by answering my questions and guiding me though challenging problems. As the O Levels approached, Kaiwen provided a wide range of practice questions and examples for each topic to help us familiarise ourselves with different question types. He also emphasised key points to take note of, which later proved extremely useful in the exams. With his support, I am happy to have secured an A1 for O Level A Math.

I attended a crash course at Zenith in Secondary 3, where I first met Kaiwen. I really appreciated how he dives deep into every concept, focusing on true understanding rather than simply having us memorise formulas. Kaiwen consistently challenges me with questions that push me to think beyond the surface and approach problems from different perspectives. He always ensures that I fully understand each topic and patiently explains concepts again if needed. He is also incredibly supportive outside of lessons, making himself available whenever I need help. Overall, it has been an amazing tuition experience, and I truly wouldn’t have achieved my results without him.

A-Math was a subject I really dreaded studying for as the content was tough and it was difficult for me to completely grasp one topic before we moved on to the next. However, this changed when I joined Kaiwen's classes after attending his crash courses during the holidays. I was initially slightly intimidated as I was not the best at A-Math and hesitated when answering in class. Despite that, Kaiwen always encouraged me to try questions myself before asking for help, which grew my confidence. I loved how we could clear our misconceptions at any point in time, and that consultations could be scheduled to clarify any remaining concerns, which helped me fill any gaps in my understanding of previous topics. Every week, I looked forward to my productive Fridays which were always filled with so much fulfilment and joy. The jokes Kaiwen cracked while we tackled monster questions he challenged us with never failed to make me laugh during the two hours of class, keeping me motivated although O-Levels was fast approaching. After a few months, I was suprised to see that I started improving and appreciating A-Math, and that I enjoyed doing homework, which is something I never thought I would say! Through the stacks of practice papers and constant revision quizzes Kaiwen gave us, I improved immensely within a year and I can confidently say this is a subject that I no longer shy away from.

I always thought that AMath was just about practicing, but Alicia helped me to understand that it was more about understanding the concepts, which made learning AMath more meaningful. She helped to break down challenging concepts and willingly repeated her explanations multiple times until we were able to grasp the concepts. She even went the extra mile to reply to our burning questions in the middle of the night at 2 am, providing a detailed explanation over text. She always made lessons so much more enjoyable, and has truly made me love AMath!

Before joining Alicia's class, I was completely demoralised after receiving an E8 for A Math. With much patience, she guided me step by step through every concept, always making sure I truly understood my workings instead of blindly copying recommended answers and moving on. With her constant encouragement and belief in me, I found the strength to persevere and eventually achieved an A1 at my O-Level exams.

Ms Alicia has been incredibly helpful throughout my upper Secondary journey. She explains concepts clearly and breaks down difficult questions into simple and logical steps, making Mathematics easy to understand. Her lessons were engaging and easy to follow, helping me to build confidence and improve my exam performance. Thanks to Alicia’s clear explanations and consistent guidance, I was able to improve from a D7 in Secondary 3 to an A1 in O Levels.

I first met Kaiwen in Secondary 2 (2023) during a crash course for Upper Secondary Math. Even though it was only a two-hour session, I genuinely felt like I learned more in those two hours than I had in my two years of lower secondary math. I came back again in Sec 4 when my A Math was at an F9. Kaiwen pushed me to attend two lessons a week to achieve the improvement I was aiming for. My original goal was just to improve from an F9 to a B4. Instead, I achieved an A2, thanks to Kaiwen!

Back in lower secondary, I did not pay much attention in class and fell far behind. As a result, I struggled to achieve good grades and even failed a weighted assessment in Secondary Three. However, Alicia helped me achieve an A1 in my O Levels. She patiently went through and explained questions repeatedly, even if she had already covered them before. She also helped me online whenever I encountered questions I did not understand. In class, she made learning engaging by incorporating fun and interactive games to test our knowledge. Additionally, she offered consultations before and after lessons, taking extra time to provide one-on-one support.

Alicia is very patient and attentive, always ensuring that her students understand every lesson taught. Her approachable nature makes her not just a teacher but also a friend, making it easy to ask questions without feeling intimidated. She explains concepts in a simple, structured, but informative way, going in depth where needed, making difficult topics easy to understand. With her guidance and support, my confidence in A Math improved greatly, and I went from a B4 in Secondary 3 EOYs to an A1 in my O Levels.

Alicia is an encouraging teacher who pushes me to look ahead. When I first joined her class, I felt hopeless due to scoring an F9 for A Math in my school exam. Alicia was clear and concise in her explanations and was always available for consultation before and after lessons, and even held online meetings. She constantly reminded me that my current grades did not define my final outcome, which motivated me to keep working hard. In the end, I improved to an A2 for my O Levels.

I used to believe that A Math was a subject I would never do well in. However, it felt like a turning point when I found myself able to confidently solve the questions Kaiwen gave us. My confidence in the subject skyrocketed as I progressed to tackling more challenging problems. With the extensive practice he provided, I began to recognise patterns in exam papers and even started to enjoy doing them. I remember that binomials had been taught before I joined his class, and when my school covered the topic, I struggled to understand it. Instead of letting me give up on the topic, Kaiwen took the time outside of regular lessons to sit down with me and go through the entire concept and its various question types. These extra consultations helped me strengthen both the areas I was weak in and the ones I was already familiar with. During the prelim period, Kaiwen even allowed us to attend lessons on other days, exposing us to a wider range of question types during a crucial time when we were doing intensive self-study. All of these efforts helped me reach my fullest potential, going from an F9 to an A1 in O-Levels!
