I have taken around 30 curses in Udemy.
When I started taking courses and prices were higher I appreciated any offer.
Now it is very common to grab offers of courses at $10 which is a real bargain.
Over the last 2 years I have noticed most of the courses I complete have a durations that last from 5 to 15 hours. Sometimes I am able to complete courses of 20 hours or more.
Courses that last less than 5 hours usually feel too short.
Courses that last more than 16 seem overwheelming, and hard to keep up when one has to combine learning and working.
So, while the 5 to 16 hours duration seems the sweet spot for me, I would like to hear from others.
What is the ideal duration of one course?
