What Our Students Have to Say

Our students have been to the best biology and chemistry tuition in Singapore, and they are all getting the grades that they deserve. Let Ms Irene help you to achieve your goals!
Dulcie IP student biology and chemistry

Miss Liu’s lessons are well-structured and well-tailored towards her students, she has an engaging teaching style and she’s flexible with lessons. Thanks to her I managed to score an A in both IP biology and chemistry for sec 4, highly recommend!

James O level express pure biology

Before Ms Irene, my biology grade was an F9, but after her tutoring, it jumped to a B3! Ms Irene is a kind and caring teacher that is able to bring out the best in every student, and her teaching methods are second to none! Tough biology questions and concepts were easily understood after she explained them with the aid of diagrams and even a 3D model!

Jasmine O level combined bio and chem

Ms liu was very helpful, she helped me understand the basics of chem and bio. Given that I went for her lessons in sec 4, I honestly thought it was too late. But she made me believe that I could do it as long as I put in hard work, which I did. So thank you Ms liu for the A2 in my cert.
