Each time you add elements, they land in a specific location in the [[Glossary:Knowledge_tree|knowledge tree]]. That location is determined by the [[Glossary:Element|element]] called the [[Glossary:Hook_node|hook]] of the default &#039;&#039;&#039;concept group&#039;&#039;&#039;. &#039;&#039;&#039;Concept groups&#039;&#039;&#039; supersede [[Glossary:Category|categories]] known from earlier SuperMemos. The main difference between &#039;&#039;&#039;concept groups&#039;&#039;&#039; and [[Glossary:Category|categories]] is that the former are associated with [[Glossary:Concept|concepts]] that play multiple roles in SuperMemo (starting with [[What&#039;s new in SuperMemo 17?|SuperMemo 17]])&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
