My wife and I have completed both the 120 day course and the Become an Online Tutor course. Both were excellent in all aspects. The only matter that we believe require improvement, is that it is a bit annoying when you are ready to upload your documents at the end of both the courses, only to find that there is a limit in terms of size and number of documents. For the online course, the size limit is provided beforehand, but the limit in documents still came as a surprise. We suggest that these limitations are made known at the beginning of each course, as well as at the end of the last section (as part of the task instructions). Thank you, Leon de Kock
