O Level Additional Mathematics Tuition

In 2019, 100% of students scored A1, A2 or B3 in O Levels

The course syllabus at The Annexe Project prepares students adequately for O Level Additional Mathematics, where a strong foundation in algebraic manipulation skills and mathematical reasoning skills are required. The content is organised into three strands, namely, Algebra, Geometry and Trigonometry, and Calculus. Besides conceptual understanding and skill proficiency built in the content strand, the development of process skills, namely, reasoning, communication and connections, thinking skills and heuristics, and applications and modelling are also emphasised.

Course Framework

Every year between August and October, our star tutor Mr Alvin Yeo will prepare his Secondary 4 students intensively through a 16- lesson Full Revision Program package followed by Mock Examinations Paper 1 and 2 set by himself that effectively prepares them to get their As. To increase the practice intensity for Additional Mathematics, O-level students can also enrol themselves into the ASTRO Program that kicks start on the first week of June yearly.

  • Joyce Pang
    CHIJ Katong Convent Secondary School
    Alvin’s willingness to go far and beyond for his students can be seen through the endless consultations he provides, even if it means staying beyond his working hours. I vividly remember the number of times I met him after lessons for consultations, sometimes even late at night, and the numerous questions that I put in front of him, which he patiently solved them without any hesitation or complain. His support and words of encouragement motivated me to push beyond my limits.
  • Zoey Lee
    Geylang Methodist Secondary School
    Upon attending Alvin’s lessons, I realised how clear and detailed his explanations of the concepts and steps in solving the problem sums were, that I finally caught a glimpse of hope for the subject. Alvin also encouraged me to join The Astro programme for A-Math where I got to do more papers that were timed to further build my momentum and work on my time management. As I slowly see my results for the Astro papers improve, my confidence also started to soar!
  • Jordan Goh Si Zhe
    Dunman High School
    Alvin was extremely motivating as he explained Math problems with such clarity that I fully understood even the most challenging Math solutions. The notes he produced were of an excellent standard, and often featured extra practices covering a wide spectrum of different problem sums of varying levels of difficulty. He extends genuine care to all his students and gives us helpful advice to better ourselves.
  • Tristan Loo
    Ngee Ann Secondary School
    Throughout my journey at The Annexe Project, my tutor Alvin, has always been a great motivator and believer in his students’ potential to achieve the best! His teaching skills are superior and sets him apart from the other tutors that I ever had. I really owe it to Alvin for helping me achieve an A2 for Mathematics in my N-levels. It was a feat that I thought I could never achieve in my wildest dreams! Thank you, Alvin!
  • Sai Shnyenn
    Chung Cheng High School (Main)
    Alvin was always there for me whenever I needed help with tough Math sums. He gave me constant guidance and even went the extra mile to schedule consultations with me. Alvin’s expertise on the subject allowed me to learn something new every lesson! Thanks to Alvin’s constant encouragement and his clarity in teaching style, I’ve maintained a strong A throughout my entire Secondary 4 journey which is something I would have never have dreamed of.

The ASTRO Program (O-Level)

The ASTRO Programme started out as an experimental and free Mathematics program in The Annexe Project in 2008 when Mr Alvin Yeo wanted to improve the results of three of his Secondary Three students Marcus Puey (Xinmin Secondary), Nicholas Yeo (Geylang Methodist Secondary) and Andrew Tan (Maris Stella High) who were struggling with their Additional Mathematics prior to the O-levels. After committing an entire year to the programme, each of the three boys eventually scored an A1 for their O-Levels examination.

The key to scoring, particularly in Mathematics, is practice, practice and… practice. Mr Alvin Yeo highly regards the importance of doing mathematic problems repeatedly within a given time frame because it helps to build momentum, confidence and trains each individual to manage time wisely. The ASTRO Program helps students to achieve academic excellence and reach the goals they have set for themselves with a simple 5-step approach.
