I feel incredible that I knew almost nothing about programming just a month ago. Now I have done two of the courses of the specialization and I can actually understand other basic codes. Great course!

Challenging for someone with zero experience with coding. Took a fairly long time to grind through the first two courses in the specialisation, but the lectures and course material were very helpful.
