Dr Kajen’s tutelage has been instrumental throughout my school journey. His deep understanding of physics and maths concepts allows me to get a much better grasp on challenging topics, and his willingness to explain things in detail, beyond the syllabus if necessary, has both fostered my enthusiasm for maths and physics as well as given me a solid foundation when faced with tricky conceptual questions that cannot just be solved by reliance on a formula. Additionally, over the years he has provided me with mentoring and guidance regarding my future academic and career goals which has allowed me to make well-informed decisions concerning subject selection and extra-curricular studies, resulting in a much better experience both socially and academically throughout my schooling time.

Dr Kajen always tries to find a way to explain difficult concepts in an easy way with much patience. He has given me many new insights into the subject to relate the knowledge to real life applications, helping me to further consolidate the knowledge. In the beginning I was failing physics bt after Dr Kajen's tutelage I have improved my U grade to a B, granting me a Most Improved Student award for H2 Physics. I am very grateful to be taught by Dr Kajen :)

I started tuition with Dr Kajen during my 2nd year in SAJC. I was moderate in secondary school physics but JC physics was much harder due to the greater breadth and depth of the syllabus. I had difficulty passing throughout my first year. I enrolled in Dr Kajen's tuition around May when I was still failing and the pressure of taking A' levels made it worse. Dr Kajen targeted the key concepts and learning points for the various topics. He is also able to explain the most complex theories in a simple way so as to improve my understanding of the subject. For the subsequent exam my grades took a turn for the better and I got a B grade. After which he focused on closing up any loopholes I had and continued stretching me with higher order questions. Dr Kajen accesses his students' abilities and chooses the best approach for them.

Mr Kajen has been such a motivational and inspiring teaches I know! From hating physics, he had successfully made me realised how important it can be and how it is applicable in our daily lives. Most of all he's been able to Develop an interest in Physics in me. He certainly has done wonders!

Dr Kajen is a great teacher! He guided me through to a grade A in Physics extended essay as well as a grade 7 in HL Physics. He doesn't just simply tell me answers, rather he pushes me to understand topics fully. Under his tutelage, I've developed problem solving skills that helped me in my exams as well as analytical skills that aided me in my various science projects.

Dr. Kajen is an effective and efficient tutor. He is patient and innovative in his approach. With his help, Amanda's grade for her Physics improved and she did well in her final IB SL Physics exam. I would not hesitate to recommend Dr. Kajen as a tutor who will help his students achieve his/her maximum potential.

Dr Kajen is an extremely patient, understanding and passionate tutor. He helped me identify the concepts that I was weak in and honed my skills to better answer math questions. He made math much more enjoyable and I am now more confident in answering a variety of problems.Also, thanks for taking me up as your student on such short notice and helping me prepare for As, I really appreciate how dedicated you were in helping me improve and gain confidence.

It was a really fun experience for me since the learning was very practical, which makes it much easier to learn. I Improved from an F9 to C6 with a month of classes

I enrolled for tuition under Dr.Kajen when i was at sec 4. I was having much difficulty with chemistry back then. I got a E8 for my sec3 SA2. After joining his tuition my grades for chemistry jumped to a C6 in SA1. During O'level i got an A2 for both my sciences. When i first went for his tuition he made me do tests to understand my weaknesses. Than he focused on my weak points. By O'levels we had already covered the entire syllabus twice. He also gave me very useful resource so that i can help myself and not depend on him for everything.Dr.Kajen analyses his studs and teaches them accordingly.

Dr.Kajen has indeed spiked my plummeting grades, in Mathematics, from D to A. He have always been there for me at all times and chased out my fear in Mathematics, using his immense knowledge in Mathematics. He thought me, how to study Maths instead of how to just solving questions or doing my homework. Thank you Dr.Kajen.

Dr. Kajen is a great teacher who has turn my grades around over the years. He’s a very friendly teacher who has always answered any questions i’ve had and helped me work through all my difficulties with the topics. After attending his tuition, he helped me understand and analyse questions a lot better and vastly improved my problem solving skills.

Initially, I felt like I had no hope for Chemistry. I was always getting F9s and borderline passes. But after I started classes, I felt that I had a better grasp on the concepts and I started to understand the techniques to doing well. Eventually, I managed a B3 for my O Levels as compared to an F9 for my prelims. It was with his teaching that I managed to overcome my obstacles. Thank you Dr Kajen!

Dr. Rasanayagam Sivasayan Kajen tutored me in IB Physics HL. I had been struggling with some of the new and more abstract topics such as quantum and particle physics. However, in a short span of time, Dr. Kajen was able to clarify everything. His in-depth understanding of the topics allowed him to provide clear and comprehensive explanations, and gave me a coherent understanding of both qualitative and quantitative concepts. With the help of Dr. Kajen, I have been predicted a Physics grade of 7 (out of a maximum of 7) for my IB exams, and I have been awarded my school’s Physics Prize. I am grateful to Dr. Kajen for imparting his knowledge to me and would recommend him to any student.

Dr. Kajen has helped me over the years in Physics (H3-Level). He made me much more interested in physics and often gave explanations on how what i learnt was applicable to real life. His lessons are free of stress and has made my learning journey a breeze.

​Dr. Kajen’s math tuition has helped me immensely over the past year. I started out very unsure and uncertain of many topics in both E Maths and A maths. However, after tuition with Dr Kajen, I have managed to have a greater understanding of maths topics, especially topics like binomial theorem and algebra. I definitely would not have been able to understand these topics and pass my exams without Dr. Kajen’s help.

Dr. Kajen helped me work through various Masters level subjects in Electrical Engineering from University College London, the subjects ranged from Digital Signal Processing and Renewable Energy to Stochastic Methods in Finance. With his help, I was able to tackle these subjects in the very short time frame of two weeks. He effortlessly broke down each subject into their essential topics that could be tackled in the limited time available to us. Thanks to him, I was able to pass the subjects and achieve an Honours degree.

The lessons were interesting and engaging. I was finally able to grasp the concepts behind the physics syllabus and thus had a better understanding of what I was learning. This allowed me to perform better for my examinations.
