Success requires not just knowledge, but years of disciplined preparation, mental resilience, and often multiple attempts. If you're preparing for any exam on this list, understand that you're competing against some of the most dedicated students in the world. Plan for 1-3 years of serious preparation, find a support community, and be prepared to treat this as a full-time commitment.
