Opening Quotes Hi Mr Alex Xu, It has been a crazy journey for me for bio in JC with me struggling to even pass. But Mr Xu gave me the opportunity to believe in myself and to always never give up. He has one of the amazing teachers I have ever had, always trying his best to ensure we grasp the concepts well and we are able to do questions. I still remember how I use to mull over my results but he always brought me up and made me stronger always taking time after lesson to teach me and explain to me until I could get it. Though I did not get my intended result, the way how my grades shot up from a fail even until my last j2 exam I can’t thank Mr Xu enough. Thank you, sir, and hope to meet u soon.   Closing Quotes

Opening Quotes  Thank you, Mr Alex, for encouraging us and making us prepared with all the important knowledge for the examination. Love the lessons which are loaded with contents yet intriguing at the same time.   Closing Quotes


Yang Zhou Yi Fan, Temasek Junior College (2017)


Opening Quotes  I hated Biology to the core before joining Mr Alex’s class. Even reading content was frustrating for me because I did not believe I could do well in the subject. Mr Alex gave us more than just notes and worksheets, he gave us moral support and encouragement all along the way. Even though it was a short few months that he took over our class for, he took the effort to always check that we were understanding what he taught and consistently asked for feedback to tailor to our needs. Those months that he taught us were the most stressful months as Prelims and As were round the corner but with his help, we were learning at a good pace and for me, I was catching up with everything I had missed out on for the past 1.5 years in a steady manner. Lessons were never a bore despite them being conducted on a weekday night which can get pretty stressful from all the mugging. Thanks to Mr Alex’s dedicated teaching, encouragement and plentiful resources, I managed to get an A for Biology despite never once achieving anything higher than an E for the subject in JC. People who say that Bio is just about memorising are not always correct! Nobody believed in my Bio grades but Mr Alex did and that made all the difference.   Closing Quotes
