About Callum Johnston

Since becoming TEFL certified in 2020, my experience includes tutoring students in the UK on a range of topics from chemistry, maths and physics to extracurricular activities such as chess. During the pandemic, I worked as an English teacher for Syrian refugees in the UK. In March 2022, I completed my face to face TEFL course here in Argentina and have been working for an institution here in Buenos Aires ever since. I now have three years of tutoring experience both in person and online, for students of all age ranges.
