Unlike most physics tutors, who are afraid to upload their academic credentials, Mr. Phang has real research experience (DSO '91-'94) and high standards of evidence.
Unlike such tutors, who cannot remember the schools they studied at but only those they coveted to teach at (Google), Mr. Phang remembers studying at RI.
Mr. Phang thus empathises with students who are brighter than their teachers

Ironically, non-scientists TheEconomicsTutor.com (fellow Rafflesian), ThatEconsTutor.com (alumnus of Hwa Chong) and EconsPhDTutor.com (alumnus of both schools) not only uploaded abundant evidence of their certificates, awards and PSLE* but also remembered their alma maters!
Top schools should hire these intellectuals to teach Physics 9749 "2.7 Make decisions based on evaluation of evidence" instead of those physics tutors they produced.
* Mr. Phang's PSLE was before T-scores but it should be well above RI's cut-off point, instead of below as is expected of tutors, based on his 2nd position in the same class as an MP (click highlighted words for evidence).
