I have 8 years' tutoring experience, 3 of which is full-time. I have taught at individual and group levels, and my students are from lower primary to upper secondary.
Most students these days are actually very intelligent but are disinterested in their studies.
I cater my teaching methods to the students' needs, and prepare as well as present the materials accordingly.
I believe that all students can learn, we just need to find the way that suits them best.
