It comes free with a 4 hr class I’m looking at taking for 100$ (roughly the cost of the kit). I have some electronic experience, but not much and no arduino experience.
The question of if it’s worth it would be based on what area of electronics you are interested in. If the kit has components that you would like to pursue, then it’s worth it. As for the class, since you didn’t give any details, we can’t answer that.
