How long must a student who fails the end-of-course exam wait before retaking the exam?

The correct timeframe for a student who fails the end-of-course exam to wait before retaking the exam is 30 days. This requirement is implemented to ensure that students have adequate time to review and grasp the course material thoroughly before attempting the exam again. This waiting period encourages better retention of knowledge and allows students to improve their chances of passing on their next attempt.

In educational programs, such policies are quite common as they promote a more effective learning environment by giving students a chance to reflect on their performance and engage with the material more deeply. Therefore, this waiting period serves both the students' learning processes and the integrity of the examination system.
