My word can I just say that the mentors on the site are absolutely stellar? A few days ago, I submitted a mentoring request to get my implementation of binary search algorithm reviewed, and while I expected a perhaps single sentence back or maybe one paragraph, I got a thorough walkthrough through my code, explaining what works well and what could be further improved or made more readable. If your username is the same on Exercism and on this forum, then thank you one more time, @neenjaw!

If you really get stuck, you can ask for mentor help
I really like the way the exercises are organised on the new site. Now there is a more coherent path to follow.

Exercism is a great site, thanks for putting a spotlight on it! I started doing some exercises there to sharpen my skills as well… just now have to wait a few more days for the site to re-launch again
