I left school a long time ago and decided to retake my O level English due to a course that I am interested in. I went to @KRTC-boon lay, previously my scored was E8 and it jumped to B3. Choosing a right tutor, is much more important than the center. My tutor is a very caring and smart lady, you should check with the center and asked about the teacher qualification(preferably ex-teacher mine was from RGSS). Good tutor will help the child understand how to answer tricky question by give out notes and worksheet that is appropriate to the child milestone . Inform them of your concern for your child and let them help you to make a wise decision. If you are unhappy with the recep, ask them when will the manager be in, as you would like to talk more about the course with someone who is well verse in the child development area. Ask them questions that worries you most, afterall parent and tutor must get along well and the end of the day, you are paying them for their service and the main objective : to get your child improve in his or hers subjects is met. Good luck and all the best in your child education.
