You can make any experience as great experience. There's a lot that goes into "good" schools, but what's most important is finding the right school for you. Some questions to ask the school & yourself:
1. Does this school help me achieve what I want to ultimately achieve? Are there any successful alumni?
2. Are the teachers going to show me how to achieve my full potential?
3. Can I feel connected to the school/teacher/student body?
4. How much help can I expect close to graduation (other schools or career)?

Other questions:
1. Average class size?
2. What happens to the graduates?
3. Average standardized test scores
4. What are the minimum qualifications of the instructors?

Good luck.
