  • Academic – Placed on the NUS Science Faculty Dean’s List

With over 16 years of teaching experience and exclusive features in the media, Mr William Lin is perhaps one of the most sought-after Chemistry Tutors in Singapore. Well-liked for his patience, clarity and ability to simplify complicated concepts, over 700 students join Making Sense every year to be coached by this award-winning Super Tutor. Mr William founded Making Sense with an aspiration to change the notion that chemistry is a mundane subject that few will excel in. He wanted students to realise that learning Chemistry need not be a struggle, and that Chemistry does have many fascinating possibilities to offer. A firm believer that learning should be fun, Mr William enlivens his lessons with stories, jokes and everyday anecdotes. He’s seen over 97% of his students show improvement in their grades, with many going on to score excellent grades in their A-level examinations. Under his tutelage, many who had believed Chemistry to be their most feared subject saw Chemistry becoming their favourite one instead. Mr William’s students not only regard him as a tutor, but as a mentor and a source of inspiration.

Mr William achieved academic excellence during his undergraduate days and was placed on the NUS Faculty of Science Dean’s List. Upon graduation, he took up a scholarship offered by NUS to pursue a PhD. in medicinal chemistry. During his scholarship, William assisted NUS as a teaching assistant and his excellence in teaching has been recognised with a “Teaching Assistance Award”. This prestigious award is presented only to the top 1% of teaching assistants out of more than 1000 candidates.

While pursuing his PhD, Mr William embarked on his exciting journey as an educator with the creation of Making Sense. Word spread quickly about his excellent teaching and within a short span of 2 years, Making Sense rapidly grew to hundreds of students. As commitments with students grew, it became increasingly difficult to manage both research studies and teaching. Having gained immense value and fulfillment in his work as an educator, Mr William decided to forgo his scholarship and devote his life to full-time teaching. While many commented that it was a waste not to complete his studies, to William, it was simply a matter of following his passion, doing what he is really good at, and choosing a path where he can genuinely make a difference in the lives of others.

Now, Mr William personally tutors more than 500 students every year. Year after year, he has never failed to inspire his students to excel in Chemistry. His students have been consistently producing exceptional results of approximately 90% As and Bs for their A’ Level. William’s extraordinary success has led to him to be featured in various media platforms, including The Straits Times and Channel NewsAsia.
