The CAD exam goes pretty deep on GlideRecord, except code snippets, CRUD operations, and scoping behavior questions, while GlideAggregate is tested more at a conceptual level, mainly around knowing when to use it over GlideRecord for performance. A classic exam trap is seeing a GlideRecord loop used for counting records when GlideAggregate is clearly the better choice so understanding the why behind each method matters more than memorizing syntax.
Did you find the exam leaned more on practical code reading or conceptual understanding when it came to these two?
