Lessons are carried out in a group setting and being a passionate and committed teacher, Mr Koh understands that some students may still have a lot of queries after lessons. As such, he always avails himself for personal consultation should a student need further coaching. All they have to do is make a prior appointment and head down to the centre in the afternoon or before lesson to seek clarification. Otherwise, he can be reached easily via SMS or Whatsapp. Consultations are free of charge as at Twig, we are excited when we see students interested in learning Chemistry and motivated to excel in the subject!
