"POA was always a boring subject for me. However after attending Caleb’s lesson, the concepts became much clearer and I could better understand POA as a subject. Not only does he makes POA a much interesting subject, he offers snacks and his signature lame jokes to make the lessons interactive and interesting as well."

"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."
