do you half to do the begginer/advanced route or can you do any route
You don't have to do a certain route for a category but there are certain checkpoints/guidelines you have to do in categories, like you can't SBLJ in 16 star you have to use Mips.
If you are new you should try those beginner and/or advanced to have a good basis to go off of, and start watching other speedrunners, near/above the skill level you might be at, and figure out what tricks you can do at that time and optimize your route to your liking.
you can do any route as long as it follows the rules of the category
