I loved this course. I enjoyed David and Zac's teaching styles as well as the graphics and video clips. The professionals interviewed were informative and well spoken. I chose not to race ahead with the course, but rather to savour each lesson. I shared what I learned with my dog-walking partner, who may now take the course herself. I appreciated learning about so many aspects of mountains from their geology to their glaciation and to the cultures of mountain people around the world. I will use the information I learned in my work. I have a biology and geography degree from long ago as was delighted to be reminded of what I already knew and to learn information that is new from when I was in school. The course was well put together. I may even take it again! I would certainly enjoy a second course on the same topic. Well done and thank you. Oh yes, and I liked the tech tips too.
