excellent teaching. the topics I couldn't possibly fathom to understand i now do, thanks to the teachings of Chegu Khairi. Big thanks to you teacher, without you, i still wouldn't have the slightest idea on how to tackle topics such as integration, probability distribution and more. i really feel like my addmath is improving exponentially because your explanation was easy to follow and understand. On top of that, your sessions was really easy to follow and didn't happen to exhaust me at all with the systematic time management of when to focus and when to take a break. i sincerely wish all the best in your life. Again, many thanks for your valiant efforts in dedicating your time and efforts to help me and the others who have participated in your tuition sessions.
