I nailed my driving test, complete with parallel parking, on the first try. But I did take driving training which was great for confidence. I also practiced with my Dad in empty parking lots first, then non-busy streets, then busy streets etc. We would practice angle parking and parallel parking quite a bit.
When I took my driving training I got a brand new Chevy red camaro and I used the same car to take my test. That helped a lot I think because I had a feel for how big it was and how it maneouvered.
