I have completed the nano degree it doesn't require actual math skills and it requires no coding skills.
But you do need some strong logical understanding to get through.
On the difficulty scale it starts of on easy note but the end sections are pretty advanced. And does need some understanding and efforts to clear through.
And a pointer if you haven't actually taken/started the subscription yet. The lesson content is available for free in Udacity, search Alteryx in Udacity search it will get you the courses which is there in the nano degree. That way you can learn the concepts then start the nano degree so that you will be better prepared. Since it's a monthly subscription it's a good idea to finish as soon as possible. Once finished all the content of nano degree will get unlocked to free.
Hope this helps 🙂
