"Caleb helped me a lot as before I joined my POA grade was C6. Then, he taught me and allowed me to understand many things I did not understand and would even crack jokes to make us remember stuff. Recently, I got an A1 for my prelims and it was all thanks to him #bestPOAtutor"

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..." Read more

"Before I met Caleb, my POA grade was a F9. I did not understand the concepts or any of the calculations. After the first few lessons, I learnt various short-cuts to simplify a question which has helped to clear my doubts for POA. Caleb’s ability to spot questions has also given me a peace of mind before exams. I can now confidently say that my POA has signif..." Read more

"Caleb has helped me tremendously. Hes been the only teacher to help me out a lot in such a short period. At first when I first started out, I had the mindset of ‘hating POA’, as I thought that POA was hard. But after joining Caleb, I didn’t know that POA was actually so doable and easy! I would always look forward to his lessons and I could actually feel mys..." Read more

I enjoyed his lessons and every week Caleb will generously provide food during h..." Read more

I used to start to hate POA when I couldn’t do POA and only when I joined your tuition and started to understand more, I did not hate it as much as I finally understood that there was a reason for why they draw up these accounts and not to kill us. Uncle! You made me have motivation to be an accountant next time."

"Before meeting Mr. Caleb, I hated POA. I didn’t get along with my POA teacher and I couldn’t understand so much. I was getting C5 to C6 grades, with just barely passes. My friend introduced me to Mr. Caleb. He was friendly, comedic and most importantly he could actually teach POA. Soon I was able to clear most of my misconceptions and by the next major exam..."
