What will I learn?
The NSI Course shows you how to design a clean console program from requirements to final submission. You will build conversational flows, apply solid input validation, and organize logic with functions and reusable data structures. Learn to model scoring and decision rules, test and debug common issues, serialize results, and deliver a documented, production-ready CLI tool in a compact, practical format.

Your classes are perfect. I purchased the one-year package and finally have the chance to follow several topics I'm interested in without needing to switch platforms... I appreciate everything you do, I've already recommended you to others...
