   Thanks for reporting this.

   This is not related to the subscription plan. The difference comes from how the API and the /practice page currently interpret category.

   Right now:

   • GET /api/v1/quizzes?category=programming filters by the older flat quiz category field, so it only returns quizzes where category = "Programming".
   • The /practice page uses the newer taxonomy system, where Programming is a top-level topic that includes subcategories like JavaScript, TypeScript, Python, React, Node.js, REST API, CSS, Data Structures, and so on.

   So the API is returning quizzes directly categorized as Programming, while the website can show quizzes from the broader Programming topic and its subcategories.

   For now, you can query specific subcategories directly, for example:

   /api/v1/quizzes?category=JavaScript
   /api/v1/quizzes?category=TypeScript
   /api/v1/quizzes?category=React
   /api/v1/quizzes?category=Python
   

   I’ll keep the existing category behavior for backward compatibility, but I should add taxonomy-aware filters such as:

   /api/v1/quizzes?topicSlug=programming
   /api/v1/quizzes?categoryId=<category_id>
   

   That would make the API match the /practice filtering behavior more closely.
