I wanted to use hierarchical metatags to separate questions into Exam > Domain > Type (like chapter questions vs final exam). However, FC0-U71 > Domain 6 > Practice Final and FC0-U71 > Domain 5 > Practice Final results in the 'Practice Final' metatag being recreated such as 'Copy(3) - Practice Final' five times in my case. I thought I could work around this by using FC0-U71 > Domain 5 | Practice Final, but then I suspected that it was going to get even more messy once I brought in another subject. Each one of the certification tests I prepare my students for has multiple domains: A+ Part 1 -> 5 Domains A+ Part 2 -> 4 Domains Networking+ -> 5 Domains Security+ -> 5 Domains You get the idea. Using hierarchical tags, I am going to wind up with 'Copy(3) - Domain 3' all over the place. For now I will try to use Exam | Domain 5 | Practice Final and see if I get copies of metatags. It's not ideal since Domain 5 is not the same subject for any exam, but I might be able to select questions by listing all three metatags if I want something like: Security+ | Domain3 | Chapter Questions
