Trust me on this: The MSF course is VERY incremental. The course starts at a most basic level, and assumes you've never seen a motorcycle. It starts from the bottom.
It progresses very incrementally, and in a manner that progresses in small steps. You learn where the parts of the bike are. You learn basic operation of switches and levers. You learn to start the bike. You begin to learn how to squeeze and ease out the clutch. At no time are you simply thrown into things...
It is fun. Simply come into it with an open mind, a willingness to learn and a little trust. Trust yourself, and trust your Rider Coach. The won't throw you to the wolves. It will all move steadily but incrementally. You'll crawl before your walk, walk before you jog, and jog before you run...
Don't chicken out !
