@Derangedvisions I am preparing for the advanced Cert as well and a little shaky on the RegEx portion. The syntax is a flip 180 for me coming from Sql and python and I am still trying to wrap my head around it. I think it is ultimately a memorizing task (coupled with frequent google search like you have mentioned). I guess I was thinking of a discussion where everyone is sharing their experiences on how to quickly tackle this challenge in daily task. I think the majority would be googling but who knows.
