"Before meeting Caleb, I only got F9 and E8 for my POA. After attending holiday classes, by CAI I got an A1. His classes are clear and easy to understand, and he also tries his best to keep us entertained and interested. If I haven’t been taught by Caleb I believe I would still be failing or couldn’t have retained my initial good grades. After one year with h..." Read more

"When I first started POA in Sec 3, I felt like a lost child in the darkness. I was clueless and lost about the subject, everytime I had a POA lesson in school I would pray that time passes quickly. My suffering stopped when I met Caleb. He was a teacher that ignites our thirst for knowledge and turns hatred for POA into love. The skills and concepts he taugh..." Read more

"Ever since I got promoted to see 4 express, I know that I will not use POA for my O level, I was buried, suffered, suffocated, lost and not motivated at all. The day I met Caleb was when I realize that I can do the impossible, I can pass POA. He made me believe in myself when I couldn’t. His positive vibe and charisma is unmatched by every educator that has..." Read more

"Before I had tuition with Caleb, I did not know a thing about POA I was scoring F9s. I was always clueless in class. Although I joined very late, after his lessons, I found myself understanding and enjoying POA more. Caleb has been a great help and I would recommend him to any POA student."

"Before I joined Caleb’s POA tuition class I had hated POA, with a low grade of F9. After joining the class I began improving and started to understand more of the concepts & theory behind it. In a few months I have achieved the humble grade of C6 with his help. I regret not joining earlier so that I could learn more under his guidance."

"Caleb’s class is very fun and he is amusing. He will find ways to make you understand the topic easily and if you don’t, he will find other ways. Class size is always ideal and the attention he gives is equal. Classroom size can be improved though. Highly effective class for POA!"

"I had never taken POA before. When I joined, I had zero knowledge about the subject. Under Caleb’s guidance, I managed to learn everything I needed to within 8 months while I’m in polytechnic. Caleb’s lessons are enjoyable and fun. While we are studying, he knows how to crack jokes and relieves our stress."
