Which sequence best fits a first-time Pennsylvania Passenger endorsement applicant who needs a skills test?

1. Apply for CDL learner processing and KTA, pass required knowledge tests, receive the CLP, complete required ELDT before skills testing, satisfy the 15-day wait, and test in a bus
2. Use the KTA as a permit, carry passengers for practice, then take a skills test without the knowledge test
3. Skip ELDT, skip the bus skills test, and add P after a vision screening
4. Take the skills test first, then apply for knowledge testing only if the road test is failed
