Who this is for
This is for you if
- You failed once and your retake is weeks out. You need the two areas that cost you, not a fresh 200-hour course.
- You are taking it the first time and want to know exactly where you stand before you spend nights studying the wrong things.
- You are a working journeyman going for your certification, studying on your phone between jobs.
Look elsewhere if
- You want a passive video course to watch front to back. We point you at the next focused step, not a semester.
- You want a guarantee you will pass. A 15-question diagnostic is not the exam, and nobody can honestly promise that.
