Blacklisted Tutor (Darrell Er, Founder of Overmugged) NTU Graduate Singapore

Darrell Er (Graduate of NTU) has been blacklisted by @sgexamspecialist for abuse and violation of our services.

He agreed on a two week commissions fee structure for engaging tutors that we recommended to him and he reneged on the deal after getting two tutors from us.

What a sneaky little tutor.

Would you want to hire someone like this as your tutor???

Update Version 1: The founder, Darrell Er, got back to me on 20th Jan 2021 in the morning, more than six months since engaging @SGExamSpecialist, to "clarify" matters. Unfortunately, it's too little too late and the management has decided to keep him on our blacklist to deter future tutors, parents and students from abusing or violating our services.

FYI, it costs an average of $10 per enquiry 2 - 3 man hours to source tutors for each qualified lead that comes into our business. It's very sad that scummy private tutors like Darrell Er would want to resort to such unethical behaviors to use our company's resources for his own benefits.

I hope the above update would adequately inform you (as an employer or vendor) of what to look out for before working with him. Thank you and have a nice day for taking the time to read my detailed 1* review! :-)


'O' Levels Chemistry & Physics Tutor

I am a NTU graduate with 7 years of private tutoring experience. I am proud to say that all of my students have gotten an A1/A2 for their 'O' levels science subjects!

I always work to ensure that my students understand the concepts and reinforce knowledge retention via consistent practice.

I also curate my own notes and have my own database of questions to help students gain more exposure of different question types.

My teaching methodology has produced an excellent track record of tutees scoring straight As for their science subjects and I do not intend to break that streak any time soon!


Group tuition - $40/hr

Private tuition - $80/hr

Feel free to reach out to me directly if you wish to work with me!
