I'm wondering does anyone here struggle to remember their course.

Recently at a show I saw a lot of people mixing up their distances as there was not much time to walk the course.

I'm wondering what tips/tricks people use to remember their course.

I saw some people writing it on their hand, others writing in the notes app on the phone, some people didn't put much effort into walking the course but preferred to watch a couple of combinations.

Do you often struggle to remember all of your distances and your "plan" for how you hope to tackle the course?

What do you do to help remember the course?

Are there any products that help with this?
