I used to think these online educational companies wouldn&#x27;t be very profitable in the long run.  Then I discovered Udemy.  In the last two months I&#x27;ve bought three courses on Udemy (at about $10-$20 each).  The courses aren&#x27;t your conventional CS classes.  I bought a course on Photoshop mastery.  Another on Android programming, and another on Adobe Illustrator skills.  I&#x27;ve enjoyed the material so far.<p>I have undergrad and grad degrees from respected US schools, so I don&#x27;t really need certification, but I still find myself taking these online courses.<p>In the case of Photoshop and Illustrator, its not even for the sake of employment (although it might be useful in the long run).  There&#x27;s something satisfying about acquiring skills in an area you are really deficient in.
