There are success and failure stories of JEE with or without external support. The choice of going for self-preparations or coaching for JEE depends upon your personality, intelligence level and budget. If you are self-determined student with high IQ, who is focused and capable of achieving targets based on self-assessment and hard work, then you can opt for self-preparation.
