Which of the following is a barrier to success in learning?

Skipping school is indeed a significant barrier to success in learning because consistent attendance is critical for absorbing the material and building knowledge over time. Regular participation in classes provides students with the opportunity to engage with the instructor, interact with peers, and practice the skills being taught. Each session often builds upon the previous ones, and missing even a single class can lead to gaps in understanding. Consequently, when a student skips school, they not only miss important lessons but also miss the opportunity to ask questions and receive immediate feedback, which is vital for effective learning. This disruption can hinder their overall academic performance and mastery of the subject matter, making it an obstacle to achieving educational success.
