English for foreign students and Maths for GCSE and lower

I am a male student who completed his GCSEs and now am looking to help others with the knowledge I have gained so far. I can speak Bangla, and a little Hindi. I have completed GCSEs in both Italian and Spanish, so I have good understanding of those languages. I am also a grade 9 maths students, so am strong enough to teach maths to those doing GCSEs or lower. This is why I am looking to teach English to foreign students and Maths. I am a very open and fun teacher, who understands the problems and struggles students have in Maths, as I have consistently taught my classmates certain Math topics. I hope to first build trust with my students, as I believe without open communication teaching cannot be efficient.
