When I was initially researching coding I visited MTStars so I am familiar with the forum. Maybe this is where I originally came across the mention of Andrews? It was in a forum-based website.
I will also say that I am still sticking to the basics taught back in Module I and II (now in Module III). I am taking my time to look up the rules and the examples in the instructional texts and code books, and it's definitely working for me. I am not moving as quickly as some, but this is what is working for me.
