Being far from an expert on this topic and without having read the entire thread, I recommend going over shifting beforehand.
I had driven a stick-shift car ever since, but I didn't feel that helped much in terms of shifting on a bike. Before taking the MSF course, my husband at the time put me on the bike with a rear stand and had me shifting up and down. He then had me ride a bit in a Home Depot shipping and receiving area after hours. I thought that helped quite a bit.
Go, DolphinRider. You will be just fine. Hope all is well!!!
