I am a First-Class Computer Systems Engineering graduate. Mathematics and Computing have been central to both my academic journey and professional experience. With 11 years of teaching and tutoring experience across GCSE and A-Level, I have developed a strong understanding of the UK curriculum and the common challenges students face. I enjoy helping students move from confusion to clarity by breaking complex topics into structured, logical steps. Beyond improving grades, my goal is to help students build confidence and develop deep, sustained understanding. I believe Mathematics and Computing should feel logical and empowering — not intimidating. I completed my BSc in Computer Systems Engineering at the University of Westminster, graduating with First-Class Honours. My degree gave me a strong foundation in programming (Python, C++, C, VHDL and Assembly), embedded systems, microcontrollers, hardware design and robotics. During my studies, I led and contributed to several technical projects, including designing FIR filters using VHDL, programming PIC and MBED microcontrollers, and developing software systems in C++ and Python. I was also recognised with academic excellence awards for my performance. Prior to university, I completed my A-Level certification at Ahmadu Bello University, studying Mathematics, Chemistry and Physics, and earlier obtained my secondary school leaving certificate at Livingstone College . Alongside my academic background, I have over 11 years of experience teaching and tutoring GCSE and A-Level Mathematics, as well as several years teaching Computing. I have worked in UK secondary schools as a Teaching Assistant supporting STEM subjects and SEN students, and as an online tutor delivering structured, results-driven lessons. My specialisation lies in Mathematics and Computer Science, particularly breaking complex, abstract ideas into logical, manageable steps that build deep and lasting understanding.

Hey I am Si Yeun! I'm a PhD student researching heterogeneous catalysts, and I have 1 year of experience tutoring Mathematics, Chemistry, Biology and Physics for GCSE and below students. Having had some tutoring myself during my GCSE period, I know how much of a nerve-wracking experience it is for both students and parents. With my lessons focusing on teaching based on the students' learning style, I hope to put those nerves at ease. Below is the list of subjects I teach and at which level. KS1/2/3: Mathematics, Science GCSE (Including IGCSE): Mathematics, Chemistry, Biology, Physics Current PhD student researching new catalysts for acetylene hydrogenation. My MSc achieved a First (1st) class classification in Materials for Energy and Environment at UCL, where I specialised in the interference of tyre wear particles with atmospheric ice nucleation. Obtained an upper second (2.1) classification for my BSc in Chemistry at Cardiff University. While my speciality is Chemistry on paper, maths and physics are integral to what I do in my current and previous research.

I’m someone who is curious, motivated, and always eager to learn. I’m currently studying an undergraduate degree in Cybersecurity at university, and I really enjoy the challenge of exploring new ideas and developing practical skills that I can use in the real world. I like learning from constructive feedback because it keeps me motivated and helps me improve, both personally and academically. Outside of my studies, I have a range of interests that I’m passionate about. I enjoy reading, as it gives me a chance to explore new perspectives and ideas. I also like staying up to date with technology—I find it fascinating how quickly things change and how innovation affects our daily lives. I’m also someone who values keeping active, so I make time to go to the gym regularly. It helps me stay focused, disciplined, and energised. I like challenges and enjoy pushing myself out of my comfort zone. For example, in Sixth Form, I chose to study Business and Law without any prior experience. It was tough at first, but fully committing to it taught me resilience, adaptability, and the importance of perseverance. I’ve found that these qualities carry over into all areas of my life, whether it’s learning something new, staying disciplined, or taking on responsibilities. Overall, I’m a person who enjoys learning, growing, and taking on challenges. I like activities that stretch me mentally and physically, and I’m motivated by opportunities that allow me to develop myself and make the most of my potential. I successfully completed my GCSEs, as well as Level 3 BTECs in Business, Law, and IT, achieving two Distinction* grades and one Distinction. In addition, I was awarded an IT certificate in Year 13, which helped deepen my knowledge and practical skills in technology. I am currently pursuing an undergraduate degree in Cybersecurity at University, where I am continuing to build my expertise in IT and develop my understanding of digital security. My education has provided a strong foundation in both academic knowledge and practical skills, preparing me for further challenges and professional growth.
