As with school, not all math teachers use the same method. You will be required to do what you have been instructed to do. Did you get a booklet or other instructions? Did you check out the DMV website for test faqs?

I stick with ith my answer in that no instructor should be giving you a bad grade for using one method vs another, unless it's an issue of safety. Remember that kids learn from parents with variable skill level. As long as you park ok without it being a safety issue or you doing something extremely weird, you should get a passing score for that.

If you want a definite answer, contact the DMV. Only they can provide that level of confidence in an answer that you are looking for.
