I always afraid of terminal after taking this course i am very comfortable ,instructor is very good explainer and guided the whole project in very practical manner.
The only thing I would change is there was a clock running on how long I could use the simulator to practice writing commands and watching the video at the same time. Once the clock run out, I could no longer type in commands as I was watching the video. I feel if I paid for the course I should be able to practice as much as I need to until I complete the course.
