The exercises are very nice. Really hard to find exercises to master this low level stuff, so this exam definitely helps.

Studying for this test (along with the associated training course) gives you the foundational knowledge that allows you to be successful as a Node.js developer.
Nov 2021
The exam was an excellent opportunity to test my knowledge of Node.js, and identify the areas I need to improve. The questions were about the things we are most likely to use when working with Node, and this gives me more confidence when developing real-world applications.
Jun 2021
Questions were good and carefully crafted.
May 2021
What I liked most about the exam, is that it really tested my practical knowledge on Node's core APIs. I have managed to apply the lessons I have learned from the course.
May 2021
It's much more comprehensive than I expected, and also harder than expected (which is good).
Mar 2021
It's cool to put into practice what we've learned in a practical manner.
Feb 2021
It was fun to write some code, good that no programming "riddles" were asked.
Jan 2021
The questions were aimed to verify the conceptual understanding and expected output, and I feel both these points are a great way to evaluate tech skills.
Jan 2021
Questions demonstrated real-world use cases.
Jan 2021
I like the practical method, writing code.
