Traditional classroom education typically requires less self-organization than studying. In a classroom setting, students have a set schedule, clear deadlines, and the guidance of a teacher to help keep them on track. On the other hand, studying independently requires more self-organization as students must manage their own time, set their own goals, and stay motivated without the structure and support of a traditional classroom environment. **

Civilian service can be completed either before or after studying, depending on the individual's circumstances and preferences. Completing civilian service before studying can provide valuable life experience and a sense of fulfillment before entering into higher education. On the other hand, completing civilian service after studying allows individuals to focus on their education first and then contribute to their community or country. Ultimately, the decision should be based on the individual's personal goals and priorities. **

Additionally, previous academic setbacks or a lack of belief in one's own capabilities can also contribute to feelings of self-doubt while studying.
