    Beginners might find some of the exercises challenging if they lack foundational knowledge, potentially leading to frustration without adequate support or guidance.
  • Limited Offline Access
    As an online tool, Practice.dev relies on an internet connection, which might limit accessibility for users who wish to practice coding offline.
  • Varied Exercise Quality
    The quality and relevance of exercises can vary, potentially leading to an inconsistent learning experience if some scenarios are not well-constructed.
