I finally finished (after 18 months) the CS50 EdX course. I started it when I decided to use much of its contents in teaching my AP Computer Science Principles course at Lincoln Sudbury. It was hard to find time to finish all the projects – the “Speller” one was the hardest for me, but I have lots of experience with web apps, so “Finance” and “Mashup” might be harder for others. I submitted the iOS app I made for Lincoln Sudbury High School as my final project – I started the current Swift version of it after I started the CS50 course so it seemed reasonable. Here is the 2 minute video I made about myLS to submit.
