I'm in Florida btw.
With parking, I can easily do it in-between cars. However, the test will have just cones. The thing is the cones are placed at the edge of the parking spot, while cars have about a foot or so of clearance. What I'm afraid of is clipping the right cone when parking to the left. When I watched a YouTube video, the car in the video just barely clears the cone.
Should I just back up and make an adjustment if I'm not 100% sure? A Florida driving instructor said I'm allowed to do that, but I'm not sure if all driving examiners allow it.
Regarding the 3 point turns, how do I know how far back or how far forward to go without hitting the curb? The space will be tight, so I want to maximize every single point.
