Ms Shabbna Feroz Khan

Education Consultant / Teacher

Ms Shabbna earned her degree from the National University of Singapore, majoring in philosophy with a minor in English Literature. Before that, she achieved a sterling academic record for English scoring A* for PSLE, A1 for O Levels and 7 out of 7 for IB English at Anglo-Chinese School (Independent).
An English Language and English Literature tutor since 2013, Shabbna strongly recognises that each child has a distinct voice and dedicates herself to honing and nurturing her students’ individual voices.


Academically, Shabbna has always excelled in the English Language and humanities. Attaining an A* and A1 for English Language in the PSLE and O Level examinations respectively, she headed to Anglo-Chinese School (Independent) where she graduated with an IB Diploma, scoring a 7 in English A1 at the Higher Level.


It was at the National University of Singapore that Shabbna found a discipline that quenched her thirst for knowledge – Philosophy. She values and encourages questioning and independent thinking, often employing the Socratic method in her teaching.
She supplemented her hunger for all things antiquity with a Minor in English Literature, which further fuelled her passion for the English Language. Every lesson she conducts becomes an opportunity to rub off good reading habits on her students.
With a strong inclination towards social service, Shabbna opted for an internship with the Ministry of Social and Family Development in 2013 where she saw first-hand the hardship some children had to endure. The experience still plays a key role in motivating her to work with children.


In every lesson, Shabbna wishes to impart her love for the language to her students, with the aim that they, too, will grow to develop their voice, speak, and be heard.
