Here I can get some comments about a piece of my code: <a href="https://codereview.stackexchange.com" rel="nofollow">https://codereview.stackexchange.com</a>
I'm not entirely sure what you are asking but I'm guessing it has something to do with how do you validate whether what you learned is correct or not.<p>I consider myself something of a self-learner and I always find some way to put what I learn into practice. Sometimes that means building something, physical or virtual, either one works. Sometimes that means discussing it with an expert.<p>Nothing teaches where you are misinformed or lack understanding like putting your knowledge into practice.
