Student since Primary School

"Our daughter has just entered JC — she had been under Mr Lim's tutelage since primary school. We went from in-centre lessons, pivoting to online sessions through Covid, then to a hybrid arrangement leading up to exams. Our daughter is now in a top JC and we are truly appreciative of Mr Lim's dedication through this whole journey!"

O-Level Math student

"Our daughter started out failing both E Math and A Math. Under Mr Lim's guidance, her confidence grew tremendously. He is structured, disciplined, and knows exactly how to identify weak areas. Koyuki achieved A1 for both E Math and A Math — a result that honestly exceeded our expectations."

O-Level E Math & A Math

"I went from C5 in E Math and C6 in A Math at Sec 3, to A1 in E Math and A2 in A Math at O Levels. Mr Lim's teaching style helped me first understand each topic, then practice until I thoroughly understood it. Joining AZKEN was likely one of the best decisions I made this year."

PSLE Math & Science

"My son scored AL5 for both Math and Science when he first joined AZKEN. With Mr Lim's dedication and teaching, he achieved AL1 in Math and AL2 in Science for PSLE. We are truly grateful for Mr Lim's effort, commitment, and care."

Student since Primary 6

"I joined Mr Lim right after prelims with an AL6 in Math. I scored AL3 at PSLE. He continued teaching me through secondary school — my Math grades are now consistently A1, always 85% and above. His clear explanations and patience have helped me build a strong foundation."

Two daughters, PSLE & O-Level

"Ken is a very dedicated teacher who has been a blessing. His perseverance and strict teaching style are core values we appreciate. My eldest has been with him since P3 — no regrets. He is the best tutor one can have."

Math since Primary School

"I have been doing Math at Azken under Mr Lim since primary school. The lesson pace suited me well. After lessons moved online during COVID, I continued online due to convenience. The online lessons remained clear and well-structured, helping me do well at O Levels."

Two children — PSLE

"Mr Lim has been a great help to both my kids, especially my older child who took his PSLE. He frequently communicated with parents about specific topics and instilled a sense of ownership — ensuring homework is completed ahead of time so he can address issues in class."

Student since Primary 2

"I've been taking Mr Lim's lessons since Primary 2. Math and Science were my strongest subjects in primary school. In secondary, E Math and A Math have always been my best subjects. I obtained A1 for both at O Levels."

P6 Maths & Science

"My son has been attending P6 Maths and Science with Mr Lim this year. Mr Lim pays close attention to weaker topics and arranges extra lessons when needed. My son achieved AL1 in Maths and AL2 in Science in his preliminary exams."
