Kaplan course question: Does access expire? Which package is best?

Hi everyone — I’m considering purchasing a course from Kaplan and I have a few questions:

1. If I buy the course, will I have access forever, or does it expire after a certain time?
2. Which package do you all recommend (self-paced vs live vs premium)?
3. Can I study the Kaplan materials without registering for the actual exam (I want to make sure I cover everything)?
4. Does it have English subtitles (or transcripts) for the lectures?
