I’m a bit confused. I see in my dashboard that there’s a section for submitted work. How does one go about doing that. And are there certain criteria for submitting work? Thanks.
The submissions link on your dashboard links you to your course excercise submissions - like in this video for example. The "Submit your work" button at the top right will take you to a page to submit your exercise along with any additional written information. These can all be later found in the aformentioned submissions section. It's great if you want to go back and check or refer to any feedback from an instructor!
Courses have challenges at the end, to test what you have learned. It's like the boss fight at the end of the course and if you beat it you'll have all the experience point, new weapons and you'll level up big time. It's a thrill to submit the exercise and be nervous for a while to see if you passed.
