I was skeptical when I enrolled in UDACITY's Data Analysis Nano Degree Program but not only have they provided the experience they said they would they have steadily made improvements since I enrolled. How many times in your life have you had that experience? Here are SOME of the improvements they have made while I have been enrolled. Initially one could get one-on-one help but usually it was 1 to 2 days out and but then it was video chat.
This was great. I had tried a competitor's course and sometime s one just cannot figure out why something is not working. But not with Udacity. Then they scrapped that and instituted a MENTOR program. Here one could instant message someone who would get back to you in a few hours. Then they scrapped that and now offer LIVE HELP. It is a chat box that one types the gist of your question into. In less than 10 min, often in 3 min , someone comes on. Usually they can immediately figure out your mistake ( it seems students make a finite # of errors) but if they cant they ask you to copy and paste your code. And if they still cannot figure it out, i.e., if you have really made a mess of things they do a screen sharing session to get you back on the rails . Don't make a mistake. Just sign up for Udacity.
