Why should an Alabama school bus applicant avoid assuming the exact number of ALEA school bus endorsement questions from a practice test?

1. FMCSA requires approved knowledge-test pools and an 80% passing standard, but ALEA may use varying test forms and does not publish a single official public item count for the S endorsement
2. The S endorsement has no knowledge test under federal rules
3. Alabama school bus testing is administered only by private websites
4. The number of questions is always identical to the passenger endorsement in every state
