Your subscription includes unlimited access to all courses, paths, and assessments, so you can revisit course lessons or retake assessments as many times as you'd like.
That said, we'd recommend taking each benchmark assessment only once, since they are designed to capture your baseline, "pre-course" ability level. After working through the course content, you may take the final assessment multiple times if you do not earn a passing mark (75%) or would like to improve your score.
