A Unique Insight into Pain Management & Business English Writing Techniques.
Kohut Academy offers both free and premium versions of 2 main courses. The first focuses on chronic pain management, the second is about improving your business English communication skills - both verbal and written. I have completed both the free introductory versions which were excellent. You get a good selection of material in normal text, PDFs, and videos. There are several quizzes too, which I found very helpful. I can heartily recommend both courses.
