Pokemon leaf green how do you get through victory road please help?

You have to get all the badges and all the HMs before you can get to the victory road, then to get through the victory road, you need to take the ladders that you havent taken before, so make notes and memorise which ones you have been through.

Sorry I cant be of more help, I started a new game and forgotten how to properly get through there.
