• Quality Variance in Problems
  The quality and difficulty of problems can vary, which may affect the consistency of the learning experience.
• Limited Real-World Project Experience
  The focus on algorithms and coding challenges means there's less emphasis on full-scale project development experience.
• Limited Feedback
  Automated grading provides limited feedback, which may not be enough for users to understand their mistakes fully.
• Subscription Costs
  Access to some premium content and features requires a subscription, which may not be affordable for all users.
