At first, I thought that it is just training like many others. But from the first session, I started changing my mind gradually. The projects are very realistic and the tutors are very experienced so the information sticks in the brain smoothly without any effort. I got my Nanodegree certificate and I feel able to really analyze any database no matter how much is big or complex thanks to UDACITY successful program. Thank you UDACITY from all my heart and I wish you more advance in this field.
