This is just to say a HUGE thank you for all your patience and guidance for A levels last year. Thank you for being wonderfully encouraging and I think that your belief in me and patience gave me a lot of confidence. Thank you for taking all the extra time to mark the practices that I did, and I appreciate all your effort in carefully explaining every single concept. I got an A in H2 chemistry for my A levels. Thank you Mr Koh!
