I have benefitted from TWIG tremendously. The detailed and concise notes and practices given helped to clear all my concepts, boosting my JC Chemistry grade from a U in J1 to A/B in J2. Mr Koh is also a passionate and helpful tutor who will go out of his way to extend help to those who need it. Joining TWIG will definitely not be a regret!
