Welcome to the Codecademy forums @bdaikis!!
I have not taken that course myself, though based on a quick glance at the lessons, it uses an online simulator to test your programs:
@bdaikis did you take the course? If the answer is yes, any reviews and commentaries?
Hey, really sorry for the 3 month AFK. I’ve been taking a short break on coding but, thanks! for the tip. I’ll probably take the course now.
