Rescue will teach you about being proactive in avoiding accidents, and will give you some techniques for coping with them when they occur. There is no harassment in the normal Rescue class.
If you want a class where you will be challenged in task loading, consider something like Intro to Tech or GUE Fundamentals. I guarantee the latter would meet your criterion of being challenging.
