First, it depends on the learners. What type of learners I am going to teach. My specialization is English Language Teaching (ELT). So I can teach all the courses related to ELT. There are so many courses that are part of ELT like Phonetics; Teaching methods, approaches, strategies; Syllabus designing, and material production. Simply request me any topic that you want to learn related to ELT and I will be ready in provided time to teach you in a comprehensible way
