"I find Caleb’s lessons and guidebook extremely useful in my assignments. Caleb has been very enthusiastic and encouraging in every lesson, clarifying our doubts no matter how long it would take. I am able to understand the topics better from the explanations, which has really helped me when I put them to practice. The guidebook is very helpful in helping me with my homework as it explains clearly my misconceptions and in my revision. I recommend any POA student to buy that book as it really helps. Thank Caleb for all your determination, believe and help! Cheers!"

Before I met Caleb, I was really at POA and I kept getting E8-F9. At that time, POA is one of my worst subjects. All the concepts and calculations were very foreign to me and there was nothing I could understand.

After I met Caleb, everything became clearer for me because I felt that his teaching method was very authentic. He helped me a lot especially on the depreciation chapter.

Moreover, his book was really useful and basically summarized everything we needed. He interacts with students and makes an effort to make the class fun and enjoyable by cracking jokes once in a while. All in all, I definitely feel more confident for the O level POA paper after I attended his tuition.
