Aloha there!
I'm a DAND graduate student, here you can see my Certificate, I've been interested and passionate about the Data science that's why I applied for the NTL scholarship and got accepted in the Data analyst nano degree program.
The DAND program was divided into 2 semester, it took me around 4 months to finish the first and another 4 months to finish the 2nd since I was just super busy with college, full time development job and another Google Challenge also on Udacity.
