Failing is the expensive way to practice
01 · Retake fees
AZ-900 retake: $99. Security+: $404. Every attempt is full price.
02 · Lockout time
NMLS SAFE MLO: $110 per attempt + a 30-day lockout between tries — fail twice and you’re 60+ days behind.
03 · Repeat odds
The retake pass rate is LOWER than the first-try rate — people who don’t change how they practice fail again.
The fix isn't more videos. It's seeing exam-format questions until nothing on test day is new.
