Both my kids attend GUG at Thomson. They used to be at MFS. GUG’s focus in on academics and preparing your kid for primary school. Phonics is a focus from PG, to lay a strong foundation for both English and Mandarin. Workbooks and worksheets are all planned and developed in-house. They are not cheap, but we paid because we agreed with the curriculum, small class sizes and the environment is clean (Not Super fanciful).
