Hello, I'm 0612

And I'm a nerd based in Singapore!

"I would never pay for tuition normally, but I realized that, more than just paying for knowledge, having you as a tutor is like paying for walking inspiration."

- A satisfied learner for one-to-one tuition

"Excellent trainer, very helpful. He is good in his field, yet able to articulate in layman's terms in his explanation. Not every trainer is able to do this."

- A Learner from a Skillsfuture-certified course

"Very passionate towards teaching. Love his way of asking questions [...] to reinforce concepts and that should be the way we think when we encounter such issues. Concise but clear in his explanation, and approachable"

- A learner from the National University of Singapore

"I like the carefree teaching style that makes students feel engaged."

- A High School Student

"I just wanted to hop in and say thank you, for having been on YouTube for so long, and for making some of the most genuine content I've seen on the platform."

- A YouTube Viewer

"[The] lecturer was systematic and clear in delivery, and provided time for hands on exercises. Lecturer displayed passion about the subject matter and made the classes very engaging. Highly increased my interest for coding."

- A learner from a Specialist Diploma programme

"The trainer is very passionate at what he teaches, and he is very patient and knowledgeable in this field. […] As a student in programming, I wished he was my lecturer in my school."

- A learner from a one-day Skillsfuture-approved course

"You made something that seemed very complex easy to comprehend. Thank you."

- A YouTube Viewer

"[He] is very clear and methodical, systematically going through the algorithms to ensure understanding."

- A High School Student

"You sir just crushed it! I love the way [you] broke those switches down Barney Style [...] There are too few videos that explain these tools with such clarity."

- Comment from a YouTube Viewer
